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

(41) And the Jews say: Ezra is the son of Allah, and the Christians say: The Messiah is the son of Allah. That is their saying with their mouths. They imitate the saying of those who disbelieved of old. Allah (Himself) fighteth against them. How perverse are they!

(42) They have taken as lords beside Allah their rabbis and their monks and the Messiah son of Mary, when they were bidden to worship only One Allah. There is no Allah save Him. Be He Glorified from all that they ascribe as partner (unto Him)!

(43) They say: Allah hath taken (unto Him) a son - Glorified be He! He hath no needs! His is all that is in the heavens and all that is in the earth. Ye have no warrant for this. Tell ye concerning Allah that which ye know not?

(44) And it sailed with them amid waves like mountains, and Noah cried unto his son - and he was standing aloof - O my son! Come ride with us, and be not with the disbelievers.

(45) And Noah cried unto his Lord and said: My Lord! Lo! my son is of my household! Surely Thy promise is the truth and Thou are the Most Just of Judges.

(46) And his people came unto him, running towards him - and before then they used to commit abominations - He said: O my people! Here are my daughters! They are purer for you. Beware of Allah, and degrade me not in (the person of) my guests. Is there not among you any upright man?

(47) He said: O my dear son! Tell not thy brethren of thy vision, lest they plot a plot against thee. Lo! Satan is for man an open foe.

(48) And he of Egypt who purchased him said unto his wife: Receive him honourably. Perchance he may prove useful to us or we may adopt him as a son. Thus we established Joseph in the land that We might teach him the interpretation of events. And Allah was predominant in His career, but most of mankind know not.

(49) And they raced with one another to the door, and she tore his shirt from behind, and they met her lord and master at the door. She said: What shall be his reward, who wisheth evil to thy folk, save prison or a painful doom?

(50) She said: This is he on whose account ye blamed me. I asked of him an evil act, but he proved continent, but if he do not my behest he verily shall be imprisoned, and verily shall be of those brought low.
