And do not argue with the People of the Scripture except in a way that is best, except for those who commit injustice among them, and say, "We believe in that which has been revealed to us and revealed to you. And our God and your God is one; and we are Muslims [in submission] to Him."29:46
It befits not (the Majesty of) Allah that He should beget a son [this refers to the slander of Christians against Allah, by saying that 'Iesa (Jesus) is the son of Allah]. Glorified (and Exalted be He above all that they associate with Him). When He decrees a thing, He only says to it, "Be!" and it is.19:35
