The word(s) "son" appears 442 time(s) in 403 verse(s) in Quran in Mohsin Khan translation.

(241) "Verily we have believed in our Lord, that He may forgive us our faults, and the magic to which you did compel us. And Allah is better as regards reward in comparison to your [Fir'aun's (Pharaoh)] reward, and more lasting (as regards punishment in comparison to your punishment)."

(242) He [Harun (Aaron)] said: "O son of my mother! Seize (me) not by my beard, nor by my head! Verily, I feared lest you should say: 'You have caused a division among the Children of Israel, and you have not respected my word!' "

(243) And thus We have sent it down as a Qur'an in Arabic, and have explained therein in detail the warnings, in order that they may fear Allah, or that it may cause them to have a lesson from it (or to have the honour for believing and acting on its teachings).

(244) (Allah) will say: "Like this: Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) came unto you, but you disregarded them (i.e. you left them, did not think deeply in them, and you turned away from them), and so this Day, you will be neglected (in the Hell-fire, away from Allah's Mercy)."

(245) And thus do We requite him who transgresses beyond bounds [i.e. commits the great sins and disobeys his Lord (Allah) and believes not in His Messengers, and His revealed Books, like this Qur'an], and believes not in the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) of his Lord; and the torment of the Hereafter is far more severe and more lasting.

(246) And if We had destroyed them with a torment before this (i.e. Messenger Muhammad صلى الله عليه وسلم and the Qur'an), they would surely have said: "Our Lord! If only You had sent us a Messenger, we should certainly have followed Your Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.), before we were humiliated and disgraced."

(247) Had We intended to take a pastime (i.e. a wife or a son), We could surely have taken it from Us, if We were going to do (that).

(248) Nay, We fling (send down) the truth (this Qur'an) against the falsehood (disbelief), so it destroys it, and behold, it (falsehood) is vanished. And woe to you for that (lie) which you ascribe (to Allah by uttering that Allah has a wife and a son).

(249) And they say: "The Most Gracious (Allah) has begotten a son (or children)." Glory to Him! They [whom they call children of Allah i.e. the angels, 'Îsa (Jesus) - son of Maryam (Mary), 'Uzair (Ezra)], are but honoured slaves.

(250) Man is created of haste. I will show you My Ayat (torments, proofs, evidence, verses, lessons, signs, revelations, etc.). So ask Me not to hasten (them).
