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

(61) And because of their saying (in boast), "We killed Messiah 'Îsa (Jesus), son of Maryam (Mary), the Messenger of Allah," - but they killed him not, nor crucified him, but it appeared so to them [the resemblance of 'Îsa (Jesus) was put over another man (and they killed that man)], and those who differ therein are full of doubts. They have no (certain) knowledge, they follow nothing but conjecture. For surely; they killed him not [i.e. 'Îsa (Jesus), son of Maryam (Mary) عليهما السلام]:

(62) And there is none of the people of the Scripture (Jews and Christians) but must believe in him ['Îsa (Jesus), son of Maryam (Mary), as only a Messenger of Allah and a human being] before his ['Îsa (Jesus) عليه السلام) or a Jew's or a Christian's] death (at the time of the appearance of the angel of death). And on the Day of Resurrection, he ['Îsa (Jesus)] will be a witness against them.

(63) Verily, We have sent the revelation to you (O Muhammad صلى الله عليه وسلم) as We sent the revelation to Nuh (Noah) and the Prophets after him; We (also) sent the revelation to Ibrahim (Abraham), Isma'il (Ishmael), Ishaq (Isaac), Ya'qub (Jacob), and Al-Asbat [the offspring of the twelve sons of Ya'qub (Jacob)], 'Îsa (Jesus), Ayyub (Job), Yunus (Jonah), Harun (Aaron), and Sulaiman (Solomon); and to Dawud (David) We gave the Zabur (Psalms).

(64) O people of the Scripture (Christians)! Do not exceed the limits in your religion, nor say of Allah aught but the truth. The Messiah 'Îsa (Jesus), son of Maryam (Mary), was (no more than) a Messenger of Allah and His Word, ("Be!" - and he was) which He bestowed on Maryam (Mary) and a spirit (Ruh ) created by Him; so believe in Allah and His Messengers. Say not: "Three (trinity)!" Cease! (it is) better for you. For Allah is (the only) One Ilah (God), glory be to Him (Far Exalted is He) above having a son. To Him belongs all that is in the heavens and all that is in the earth. And Allah is All-Sufficient as a Disposer of affairs.

(65) And those who disbelieve and deny our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) are those who will be the dwellers of the Hell-fire.

(66) Surely, in disbelief are they who say that Allah is the Messiah, son of Maryam (Mary) . Say (O Muhammad صلى الله عليه وسلم): "Who then has the least power against Allah, if He were to destroy the Messiah, son of Maryam (Mary), his mother, and all those who are on the earth together?" And to Allah belongs the dominion of the heavens and the earth, and all that is between them. He creates what He wills. And Allah is Able to do all things.

(67) And (O Muhammad صلى الله عليه وسلم) recite to them (the Jews) the story of the two sons of Adam (Habil and Qabil-Abel and Cain) in truth; when each offered a sacrifice (to Allah), it was accepted from the one but not from the other. The latter said to the former: "I will surely kill you. " The former said: "Verily, Allah accepts only from those who are Al-Muttaqun (the pious - See V.2:2)."

(68) Because of that We ordained for the Children of Israel that if anyone killed a person not in retaliation of murder, or (and) to spread mischief in the land - it would be as if he killed all mankind, and if anyone saved a life, it would be as if he saved the life of all mankind. And indeed, there came to them Our Messengers with clear proofs, evidence, and signs, even then after that many of them continued to exceed the limits (e.g. by doing oppression unjustly and exceeding beyond the limits set by Allah by committing the major sins) in the land!

(69) And in their footsteps, We sent 'Îsa (Jesus), son of Maryam (Mary), confirming the Taurat (Torah) that had come before him, and We gave him the Injeel (Gospel), in which was guidance and light and confirmation of the Taurat (Torah) that had come before it, a guidance and an admonition for Al-Muttaqun (the pious - See V.2:2).

(70) Say: "O people of the Scripture (Jews and Christians)! Do you criticize us for no other reason than that we believe in Allah, and in (the revelation) which has been sent down to us and in that which has been sent down before (us), and that most of you are Fasiqun [rebellious and disobedient (to Allah)]?"
