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

(361) These are the Ayat (proofs, evidence, verses, lessons, revelations, etc.) of Allah, which We recite to you (O Muhammad صلى الله عليه و سلم) with truth. Then in which speech after Allah and His Ayat will they believe?

(362) This (Qur'an) is a guidance. And those who disbelieve in the Ayat (proofs, evidence, verses, lessons, signs, revelations) of their Lord, for them there is a painful torment of Rijz (a severe kind of punishment).

(364) But he who says to his parents: "Fie upon you both! Do you hold out the promise to me that I shall be raised up (again) when generations before me have passed away (without rising)?" While they (father and mother) invoke Allah for help (and rebuke their son): "Woe to you! Believe! Verily, the Promise of Allah is true." But he says: "This is nothing but the tales of the ancient."

(365) And indeed We have destroyed towns (populations) round about you, and We have (repeatedly) shown (them) the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) in various ways that they might return (to the truth and believe in the Oneness of Allah - Islamic Monotheism).

(366) And (remember) when We sent towards you (Muhammad صلى الله عليه وسلم) a group (three to ten persons) of the jinn, (quietly) listening to the Qur'an. When they stood in the presence thereof, they said: "Listen in silence!" And when it was finished, they returned to their people, as warners.

(367) O you who believe! If a Fasiq (liar - evil person) comes to you with any news, verify it, lest you should harm people in ignorance, and afterwards you become regretful for what you have done.

(368) And every person will come forth along with an (angel) to drive (him) and an (angel) to bear witness.

(369) Then he conceived fear of them (when they ate not). They said: "Fear not." And they gave him glad tidings of a son having knowledge (about Allah and His religion of True Monotheism).
