The word(s) "son" appears 151 time(s) in 132 verse(s) in Quran in Muhammad Pickthal translation.

(111) Did I not charge you, O ye sons of Adam, that ye worship not the devil - Lo! he is your open foe! -

(112) So We gave him tidings of a gentle son.

(113) And when (his son) was old enough to walk with him, (Abraham) said: O my dear son, I have seen in a dream that I must sacrifice thee. So look, what thinkest thou? He said: O my father! Do that which thou art commanded. Allah willing, thou shalt find me of the steadfast.

(114) Now ask them (O Muhammad): Hath thy Lord daughters whereas they have sons?

(115) (And again of their falsehood): He hath preferred daughters to sons.

(116) If Allah had willed to choose a son, He could have chosen what He would of that which He hath created. Be He Glorified! He is Allah, the One, the Absolute.

(117) And when he brought them the Truth from Our presence, they said: Slay the sons of those who believe with him, and spare their women. But the plot of disbelievers is in naught but error.

(118) Or chooseth He daughters of all that He hath created, and honoureth He you with sons?

(119) And when the son of Mary is quoted as an example, behold! the folk laugh out,

(120) Say (O Muhammad): If the Beneficent One hath a son, then, I shall be first among the worshippers. (But there is no son).
