We can all assume that anyone subscribing to Islam will think the Koran does not contain a mistake and the passage you cite is correct.

Some denominations of Christianity, Catholics I believe, pray to Mother Mary. They may perceive her simply as an intercessor, but in the eyes of Islam, it is the same as taking a God. http://www.turnbacktogod.com/should-we-pray-to-virgin-mary/ http://www.wikihow.com/Pray-to-the-Virgin-Mary

quran doesn't say the persons of the trinity are father, son and Mary but say that who worship Jesus or mary he will be in the hell in another verses quran said (they disbelive who say god is one of three gods) he say nothing about the persons of trinity in this verse

Islam does not in any way, shape or form accept the concept of a trinity or triune deity. Muslims believe that such a concept is a violation of the essential "oneness" of the godhead. I'm not saying that the view is correct or incorrect, only that in terms of Islam it would be blasphemous.

I want you to show us Where in the Noble Quran Allah says that the three persons of the false christian Trinity dogma are the Father, Son, and the mother of Jesus !!? No where. Here is the verse you refer to in your question which is (Quran 5:116): [116] "And (remember) when Allah will say (on the Day of Resurrection): "O 'Isa (Jesus), son of Maryam (Mary)! Did you say unto men: 'Worship me and my mother as two gods besides Allah?' " He will say: "Glory be to You! It was not for me to say what I had no right (to say). Had I said such a thing, You would surely have known it. You know what is in my inner-self though I do not know what is in Yours; truly, You, only You, are the All-Knower of all that is hidden (and unseen)." [The Noble Quran 5:116]. - It is clear that Allah in the above verse states that some Christians (infact the majority: Catholics) also consider(ed) the mother of Jesus (PBUH) to have the same exact titles which belong to Jesus alone. They treat her as a Divine person and they pray to her. In Roman Catholicism, Mary is more than human. In the Catholic Religion it is stated that: "Mary...Is called Queen of Heaven (worshipping the "queen of heaven" is actually mentioned in Jeremiah 7:17-19 as worshipping another god), the All Holy One, the life, hope, way to God, The Mother of Mercy, Our Blessed Lady, Our Blessed Virgin...in fact, she is given the same exact titles which belong to Jesus alone—Life, Hope, the Way, Morningstar, etc and she has more names and titles than the Bible has for Jesus." Why do Catholics Pray to Mary http://www.catholictradition.org/Mary/mary.htm Do Catholics Worship the Mother Mary? And if they do, is it against God's Word? http://www.biblestudysite.com/mary.htm

The verse you have pointed out is ..................Then Allah will say : 'Isa(Jesus) son of Maryam(Mary), did you ever say to mankind: "Worship me and my mother as gods besides Allah"' 'Glory to You,' he will answer, 'How could I say that to which I have no right? If I had ever said so, you would have surely known it. you know what is in my mind but I can not tell what is in Yours................... I think you have been reading the wrong Quran or the on you read was interpreted wrongly. If you read the previous verses you will come to this point that Allah will one day gather all the apostles and ask Jesus if he ever told the world to worship him
