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

(341) (He is Allah) Owner of High Ranks and Degrees, the Owner of the Throne. He sends the revelation by His Command to any of His slaves He wills, that he (the person who receives revelation) may warn (men) of the Day of Mutual Meeting (i.e. the Day of Resurrection).

(342) This Day shall every person be recompensed for what he earned. This Day no injustice (shall be done to anybody). Truly, Allah is Swift in reckoning.

(343) And indeed We sent Musa (Moses) with Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.), and a manifest authority,

(344) Then, when he brought them the Truth from Us, they said: "Kill the sons of those who believe with him and let their women live"; but the plots of disbelievers are nothing but in vain!

(345) Those who dispute about the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) of Allah, without any authority that has come to them, it is greatly hateful and disgusting to Allah and to those who believe. Thus does Allah seal up the heart of every arrogant, tyrant. (So they cannot guide themselves to the Right Path).

(346) Verily those who dispute about the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) of Allah, without any authority having come to them, there is nothing else in their breasts except pride [to accept you (Muhammad صلى الله عليه وسلم) as a Messenger of Allah and to obey you] . They will never have it (i.e. Prophethood which Allah has bestowed upon you). So seek refuge in Allah (O Muhammad صلى الله عليه وسلم from the arrogants). Verily, it is He Who is the All-Hearer, the All-Seer.

(347) Thus were turned away those who used to deny the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) of Allah.

(348) See you not those who dispute about the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) of Allah? How are they turning away [from the truth, (i.e. Islamic Monotheism to the falsehood (i.e. polytheism)]?

(349) As for 'Ad, they were arrogant in the land without right, and they said: "Who is mightier than us in strength?" See they not that Allah, Who created them was mightier in strength than them. And they used to deny Our Ayat (proofs, evidence, verses, lessons, revelations, etc.)!

(350) That is the recompense of the enemies of Allah: the Fire. Therein will be for them the eternal home, a (deserving) recompense for that they used to deny Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.).
