Like the Bible, the Qur'an is sometimes vague and open to interpretation. Granted I do not read Arabic, I can only look through the English translation. The Qur'an definitely teaches that it is wrong to lie. Biggest problem is the interpretation of what things mean. Sooner or later someone will make it mean whatever suites there desire. Be that benevolent or hate driven.

I'm no expert but I don't believe that the Quran has a different moral structure for the treatment of infidels and believers. Just as, generally speaking, the Bible doesn't.

It is very difficult to say. I've read it only once, but there are lots of different translations, and it's tricky for someone to translate anyway, since the original was in poem form. Since poems have 'between the lines' meanings too. There are some passages with regard to converting non-followers, talking about 'freeing' or 'enlightening' them.

The Qur’an does not teach it is Ok to Lie or to kill non-aggressive non-believers. There are a few verses that indicate that it is sometimes ok to hide the truth but only in extreme cases. These allowances are only for your own safety, for example if someone is killing all the Muslims in an area and they say are you Muslim and you say no this lie wouldn’t be held against you because it is reached under duress. It does allow for violence against non-believers only in defense of your home, life or country as well as defense of those unable to defend themselves. However the Qur’an is very clear that we are not to be aggressors. Lying 16:106 (Asad) As for anyone who denies God after having once attained to faith-and this, to be sure, does not apply to one who does it under duress, the while his heart remains true to his faith, but [only, to] him who willingly opens up his heart to a denial of the truth-: upon all such [falls] God's condemnation, and tremendous suffering awaits them: Man kafara biAllahi min baAAdi eemanihi illa man okriha waqalbuhu mutmainnun bialeemani walakin man sharaha bialkufri sadran faAAalayhim ghadabun mina Allahi walahum AAathabun AAatheemun 2:225 (Asad) God will not take you to task for oaths which you may have uttered without thought, but will take you to task [only] for what your hearts have conceived [in earnest]: for God is much-forgiving, forbearing. La yuakhithukumu Allahu biallaghwi fee aymanikum walakin yuakhithukum bima kasabat quloobukum waAllahu ghafoorun haleemun Violence 2:190 (Asad) AND FIGHT in God's cause against those who wage war against you, but do not commit aggression-for, verily, God does not love aggressors. Waqatiloo fee sabeeli Allahi allatheena yuqatiloonakum wala taAAtadoo inna Allaha la yuhibbu almuAAtadeena 4:91 (Asad) You will find [that there are] others who would like to be safe from you as well as safe from their own folk, [but who,] whenever they are faced anew with temptation to evil, plunge into it headlong. Hence, if they do not let you be, and do not offer you peace, and do not stay their hands, seize them and slay them whenever you come upon them: for it is against these that We have clearly empowered you [to make war]. Satajidoona akhareena yureedoona an yamanookum wayamanoo qawmahum kulla ma ruddoo ila alfitnati orkisoo feeha fain lam yaAAtazilookum wayulqoo ilaykumu alssalama wayakuffoo aydiyahum fakhuthoohum waoqtuloohum haythu thaqiftumoohum waolaikum jaAAalna lakum AAalayhim sultanan mubeenan 22:39 (Asad) PERMISSION [to fight] is given to those against whom war is being wrongfully waged and, verily, God has indeed the power to succor them Othina lillatheena yuqataloona biannahum thulimoo wainna Allaha AAala nasrihim laqadeerun 60:8 (Asad) As for such [of the unbelievers] as do not fight against you on account of [your] faith, and neither drive you forth from your homelands, God does not forbid you to show them kindness and to behave towards them with full equity: for, verily, God loves those who act equitably La yanhakumu Allahu AAani allatheena lam yuqatilookum fee alddeeni walam yukhrijookum min diyarikum an tabarroohum watuqsitoo ilayhim inna Allaha yuhibbu almuqsiteena These verses lay down unequivocally that only self-defense (in the widest sense of the word) makes war permissible for Muslims. Most of the commentators agree in that the expression la ta'tadu signifies, in this context, "do not commit aggression"; while by al mu'tadin "those who commit aggression" are meant. The defensive character of a fight "in God's cause" - that is, in the cause of the ethical principles ordained by God - is, moreover, self-evident in the reference to "those who wage war against you", and has been still further clarified in 22:39 - "permission [to fight] is given to those against whom war is being wrongfully waged" - which, according to all available Traditions, constitutes the earliest (and therefore fundamental) Qur'anic reference to the question of jihad as holy war (see Tabari and Ibn Kathir in their commentaries on 22: 39 ). That this early, fundamental principle of self-defense as the only possible justification of war has been maintained throughout the Qur'an is evident from 60:8, as well as from the concluding sentence of 4:91

From my understanding and how it has been interpreted to me, no to both counts. There are interpretations out there, like any religious text, that say otherwise. Radical Clerics have issued Fatwahs proclaiming we non beleivers be slayed. Then again, there are a few Christian nuts who have their own particular take on the Bible that stray from it's original meaning too. Times change, religious texts rarely do to keep up with those times. I could point to a case in the last year or so of a man who'd converted to christianity from Islam and was sentenced to death over it. Two cases actually since I judt did a quick google on it to back this up: http://www.cnn.com/2006/WORLD/meast/03/21/afghan.christian/ http://www.militantislammonitor.org/article/id/689 I make no representation that either of those sites are 100% unbiased, but the Afghan man was widely reported here and I recall our Ambassador trying for leniency for him.

Sura V - The Table, 5:51 -- O Believers! take not the Jews or Christians as friends. They are but one another's friends. If any one of you taketh them for his friends, he surely is one of them! God will not guide the evil doers. . So shalt thou see the diseased at heart speed away to them, and say, "We fear lest a change of fortune befall us." But haply God will of himself bring about some victory or event of His own ordering: then soon will they repent them of their secret imaginings. . . However, later in the same chapter: . Those that make war against God and His apostle and spread disorder in the land shall be slain or crucified or have their hands and feet cut off on alternate sides, or be banished from the land. They shall be held up to shame in this world and sternly punished in the hereafter: except those that repent before you reduce them. . . So it looks like it is dependent on the circumstance, although I am only beginning to learn about the Koran. I could be wrong in my understanding.

"Infidel" is not exclusive to Islam. Infidel (literally "one without faith") is an English word meaning "one who doubts or rejects central tenets of a religion or has no religious beliefs", especially in reference to Christianity or Islam.[1][2][3][4][5] In Christianity, the term was traditionally used by the Roman Catholic Church to refer to one who did not believe in the divinity of Jesus, knowingly held beliefs that contradicted Catholic dogma, or who had not been baptized,[6][7] or by Christians in general to describe non-Christians or those perceived as enemies of Christianity, including Muslims.

no the islam not teach us to lie or kill The Quran says, "Truly Allah guides not one who transgresses and lies." Surah 40:28. Holy Quran in another place saying:"Do not kill a soul which Allah has made sacred except through the due process of law ... (6:151) " . , the word " soul " is significant , it refers to all people

There is no punishment for apostasy in Islam. In fact the Qur’an stresses kindness and tolerance in matters of faith, the perfect example being the verse of the Holy Qur’an: There should be no compulsion in religion. (Ch.2: V.257), Islam stresses the freedom of religion, for example in Chapter 109 of the Holy Qur’an it states, For you your religion, and for me my religion Furthermore there is not a single example of any punishment for apostasy from the life of the Holy Prophet(saw). The Qur’an states very clearly, that those who leave the Islamic faith and apostatise will be dealt with only by God Himself: Those who believe, then disbelieve, then again believe, then disbelieve and then increase in disbelief, Allah will never forgive them nor will He guide them to the way. (Ch.4: V.138) Nowhere is any punishment prescribed in this life as religion is a personal matter between man and God. People are therefore free to believe in any religion and to change their beliefs without any punishment from man. They will, however, be accountable for their beliefs before God.

This is a quote from the Quran: “Fight and kill the disbelievers wherever you find them, take them captive, harass them, lie in wait and ambush them using every stratagem of war.” Self-explanatory...... Source: http://www.orthodoxytoday.org/blog/2009/11/12/does-islam-breed-violence/

There are some verses which tend to suggest that

@topic starter if you are really sincere in knowing the answer, you should probably ask some learned islamic scholar about it. you can google it as well. you don't ask about severe medical problems on a forum, do you? same is the case with religious queries, u need to consult a scholar for that. :)

Kill everybody. Get it over with.

According to Sharia Laws (extracted from the Quran and Hadith) , apostates of Islam must be sentenced to death. This has led to ex-Muslims often being persecuted, abused and killed. [Muslims read the qu'ran and hadith] Hadith, Sahih Bukhari 4:52:260 speaks about apostasy and apostates I suggest you read it for yourself.

Yes. One is receiving many lies from the Muslims in the other answers. They will twist and rationalise all they want, but Allah wanted such words to be recorded in the Q'uran. Only evil people are disbelievers. 2:99 War is ordained by Allah, and all Muslims must be willing to fight, whether they like it or not. 2:216 The disbelievers, they are the wrong-doers. 2:254 Don't believe anyone who is not a Muslim. 3:73 Do not obey disbelievers. 3:149 Oppose and admonish those who refuse to follow Muhammad. 4:63 Believers fight for Allah; disbelievers fight for the devil. So fight the minions of the devil. 4:76 The disbelievers are an open enemy to you. 4:101 Non-muslims are wrong doers. 5:45 Evil is the handiwork of the rabbis and priests. 5:63 Disbelief is the greatest evil. 7:37 Disbelievers are liars. 7:66 Slay the idolaters wherever you find them. 9:5 Fight the disbelievers and hypocrites. Be harsh with them. They are all going to hell anyway. 9:73 Stay away from non-Muslims. They are all liars. 9:107 "He maketh none to share in His government." Democracy is heresy. Allah shares his government with no one. 18:26 Shall I continue? http://skepticsannotatedbible.com/quran/index.htm

1) "Lying in the Quran Allah knows the secrets of all hearts [42:24] and knows when one lies [9:42]. Thus one cannot frustrate Allah by falsehood [9:2], which is bound to perish [17:81] and those who lie destroy their souls [9:42]. Liars will be called to account on the Day of Judgements [29:13][45:27][58:18] and Allah will not guide them [40:28][61:7]. Woe to sinful liars! [45:7][51:10][52:11][96:16] The following are particularly noted for punishment: shameful lies of idolaters [7:152][18:15], liars who disunite believers [9:107], those who lie that all good things are for themselves [16:62], hypocrites [59:11][63:1], those who lie against Allah when invited to Islam [61:7] or who treat Allah's signs as falsehoods [64:10]. The Quran gives this formula to judge who is culpable in an accusation of rape: If his shirt is rent from the front, then is her tale true, and he is a liar! But if his shirt is torn from the back, then is she the liar, and he is telling the truth![12:26,27]" Source and further information: http://en.wikipedia.org/wiki/Lie#Lying_in_the_Quran 2) "Within the Shia theological framework, the concept of Taqiyya (تقية - 'fear, guard against', also taghiyeh) refers to a dispensation allowing believers to conceal their faith when under threat, persecution or compulsion. The word "al-Taqiyya" literally means: "Concealing or disguising one's beliefs, convictions, ideas, feelings, opinions, and/or strategies at a time of imminent danger, whether now or later in time, to save oneself from physical and/or mental injury." A one-word translation would be "dissimulation." " "Shi'i View An eminent Shia authority, Ayatollah Sistani describes the concept of Taqiyya as follows: "1)Taqiyah is done for safety reasons. For example, a person fears that he might be killed or harmed, if he does not observe Taqiyah. In this case, it is obligatory to observe Taqiyah. 2) Reconciliatory Taqiyah. This type of Taqiyah is done when a person intends to reconcile with the other side or when he intends to soften their hearts. This kind of Taqiyah is permissible but not obligatory. 3) Sometimes, Taqiyah may cause a more important obligation to be lost or missed, if so it is forbidden. For example, when I know that silence would cause oppression and infidelity to spread and will make people go astray, in such a situation it is not permissible to be silent and to dissimulate. 4) Sometimes, Taqiyah may lead to the death of an innocent person. If so, it is not permissible. It is therefore haram (forbidden) to kill a human being to save your own life." The Taqiyah doctrine is based on the following verse from Qur'an 3:28: "Let not the believers take for friends or helpers unbelievers rather than believers. If any do that, in nothing will there be help from Allah; except by way of precaution, that ye may guard yourselves from them". Sunni commentator Ibn Kathir explained that "believers that fear for their safety from the unbelievers... are allowed to show friendship to the unbelievers outwardly, but never inwardly". According to the Shia scholar Muhammad Husain Jafari Sahiwal, Shi'ism would not have spread if it wasn't for taqqiyah. (Referring to instances where Shiites have been ruthlessly persecuted by the Sunni political elite, during the Umayyad and Abbasid empires" Source and further information: http://en.wikipedia.org/wiki/Taqiyya

I suggest read the quran. It is not that difficult or daunting, and is available online in several places inclding http://etext.virginia.edu/koran.html . Just how much you can trust the believers to tell the truth, and the principles by which they may not, is already covered in other answers.
