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

(1) But those who disbelieve and belie Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) - such are the dwellers of the Fire. They shall abide therein forever.

(2) And fear a Day (of Judgement) when a person shall not avail another, nor will intercession be accepted from him nor will compensation be taken from him nor will they be helped.

(3) And (remember) when We delivered you from Fir'aun's (Pharaoh) people, who were afflicting you with a horrible torment, killing your sons and sparing your women, and therein was a mighty trial from your Lord.

(4) And (remember) when you said, "O Musa (Moses)! We cannot endure one kind of food. So invoke your Lord for us to bring forth for us of what the earth grows, its herbs, its cucumbers, its Fum (wheat or garlic), its lentils and its onions." He said, "Would you exchange that which is better for that which is lower? Go you down to any town and you shall find what you want!" And they were covered with humiliation and misery, and they drew on themselves the Wrath of Allah. That was because they used to disbelieve the Ayat (proofs, evidence, verses, lessons, signs, revelations etc.) of Allah and killed the Prophets wrongfully. That was because they disobeyed and used to transgress the bounds (in their disobedience to Allah, i.e. commit crimes and sins).

(5) So We made this punishment an example to their own and to succeeding generations and a lesson to those who are Al-Muttaqun (the pious - See V.2:2).

(6) So We said: "Strike him (the dead man) with a piece of it (the cow)." Thus Allah brings the dead to life and shows you His Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) so that you may understand.

(7) And indeed, We gave Musa (Moses) the Book and followed him up with a succession of Messengers. And We gave 'Îsa (Jesus), the son of Maryam (Mary), clear signs and supported him with Ruh-ul-Qudus [Jibrael (Gabriel عليه السلام)]. Is it that whenever there came to you a Messenger with what you yourselves desired not, you grew arrogant? Some you disbelieved and some you killed.

(8) And they (Jews, Christians and pagans) say: Allah has begotten a son (children or offspring) . Glory be to Him (Exalted be He above all that they associate with Him). Nay, to Him belongs all that is in the heavens and on earth, and all surrender with obedience (in worship) to Him.

(9) And fear the Day (of Judgement) when no person shall avail another, nor shall compensation be accepted from him, nor shall intercession be of use to him, nor shall they be helped.

(10) And (remember) when Ibrahim (Abraham) and (his son) Isma'il (Ishmael) were raising the foundations of the House (the Ka'bah at Makkah), (saying), "Our Lord! Accept (this service) from us. Verily! You are the All-Hearer, the All-Knower."
