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

(231) (The angel) said: "I am only a messenger from your Lord, (to announce) to you the gift of a righteous son."

(232) She said: "How can I have a son, when no man has touched me, nor am I unchaste?"

(233) Such is 'Îsa (Jesus), son of Maryam (Mary). (It is) a statement of truth, about which they doubt (or dispute).

(234) It befits not (the Majesty of) Allah that He should beget a son [this refers to the slander of Christians against Allah, by saying that 'Îsa (Jesus) is the son of Allah]. Glorified (and Exalted) be He (above all that they associate with Him). When He decrees a thing, He only says to it: "Be!" - and it is.

(235) Then the sects differed [i.e. the Christians about 'Îsa (Jesus) عليه السلام], so woe unto the disbelievers [those who gave false witness by saying that 'Îsa (Jesus) is the son of Allah] from the Meeting of a great Day (i.e. the Day of Resurrection, when they will be thrown in the blazing Fire) .

(236) And they say: "The Most Gracious (Allah) has begotten a son (or offspring or children) [as the Jews say: 'Uzair (Ezra) is the son of Allah, and the Christians say that He has begotten a son ['Îsa (Jesus) عليه السلام], and the pagan Arabs say that He has begotten daughters (angels and others.)]."

(237) That they ascribe a son (or offspring or children) to the Most Gracious (Allah).

(238) But it is not suitable for (the Majesty of) the Most Gracious (Allah) that He should beget a son (or offspring or children).

(239) "Verily, the Hour is coming - and I am almost hiding it from Myself - that every person may be rewarded for that which he strives.

(240) "Go you and your brother with My Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.), and do not, you both, slacken and become weak in My Remembrance.
