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

(131) Those who reject Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.), We shall gradually seize them with punishment in ways they perceive not.

(132) It is He Who has created you from a single person (Adam), and (then) He has created from him his wife [Hawwa' (Eve)], in order that he might enjoy the pleasure of living with her. When he (a polytheist from Adam's offspring - as stated by Ibn Kathir in his Tafsir) had sexual relation with her (the polytheist's wife), she became pregnant and she carried it about lightly. Then when it became heavy, they both invoked Allah, their Lord (saying): "If You give us a Salih (good in every aspect) child, we shall indeed be among the grateful."

(133) O you who believe! Answer Allah (by obeying Him) and (His) Messenger when he (صلى الله عليه وسلم) calls you to that which will give you life, and know that Allah comes in between a person and his heart (i.e. He prevents an evil person to decide anything). And verily to Him you shall (all) be gathered.

(134) And (remember) when the disbelievers plotted against you (O Muhammad صلى الله عليه وسلم) to imprison you, or to kill you, or to get you out (from your home, i.e. Makkah); they were plotting and Allah too was plotting; and Allah is the Best of those who plot.

(135) Similar to the behaviour of the people of Fir'aun (Pharaoh), and those before them. They belied the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) of their Lord, so We destroyed them for their sins, and We drowned the people of Fir'aun (Pharaoh) for they were all Zalimun (polytheists and wrong-doers).

(136) So if you gain the mastery over them in war, punish them severely in order to disperse those who are behind them, so that they may learn a lesson.

(137) O Prophet (Muhammad صلى الله عليه وسلم)! Urge the believers to fight. If there are twenty steadfast persons amongst you, they will overcome two hundreds, and if there be a hundred steadfast persons they will overcome a thousand of those who disbelieve, because they (the disbelievers) are people who do not understand.

(138) Now Allah has lightened your (task), for He knows that there is weakness in you. So if there are of you a hundred steadfast persons, they shall overcome two hundreds, and if there are a thousand of you, they shall overcome two thousand with the Leave of Allah. And Allah is with As-Sabirun (the patient).

(139) It is not for a Prophet that he should have prisoners of war (and free them with ransom) until he had made a great slaughter (among his enemies) in the land. You desire the good of this world (i.e. the money of ransom for freeing the captives), but Allah desires (for you) the Hereafter. And Allah is All-Mighty, All-Wise.

(140) They have purchased with the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) of Allah a little gain, and they hindered men from His Way; evil indeed is that which they used to do.
