well you christians say Jesus is the son..
now When Allah says "They say: "Allah hath begotten a son": Glory be to Him, nay, to Him belongs all that is in the heavens and on earth: everything renders worship to Him. (The Qur’an El-Bagarah 116)
Now you play with the words. you are the ones who say Allah has a son.. now you twist and saying something else..
Come one ask any christian they will say Jesus pbuh is the son of Allah.
