"O people of the Scripture! Do not exaggerate in your religion nor utter aught concerning Allah save the truth. The Messiah, Jesus son of Mary, was only a messenger of Allah, and His word which he conveyed unto Mary, and a spirit [sic.] from Him. So believe in Allah and His messengers and say not 'Three' - Cease! (it is better for you! - Allah is only one God. Far is it removed from His transcendent majesty that He should have a son...The Messiah will never scorn to be a slave unto Allah." Quran [004.171] see also [005.073]

"And when the son of Mary is quoted as an example, behold! The folk laugh out, and say: Are our gods better, or is he? They raise not the objection save for argument. Nay! but they are a contentious folk. He is nothing but a slave on whom we bestowed favor, and we made him a pattern for the Children of Israel. And had we willed it we would have set among you angels to be viceroys in the earth". Quran [043.057-060]
