The word(s) "oh" appears 123 time(s) in 113 verse(s) in Quran in Mohsin Khan translation.

(31) And We took the Children of Israel across the sea, and Fir'aun (Pharaoh) with his hosts followed them in oppression and enmity, till when drowning overtook him, he said: "I believe that none has the right to be worshipped but He (Allah) in Whom the Children of Israel believe, and I am one of the Muslims (those who submit to Allah's Will)."

(32) To Fir'aun (Pharaoh) and his chiefs, but they followed the command of Fir'aun (Pharaoh), and the command of Fir'aun (Pharaoh) was no right guide.

(33) If only there had been among the generations before you persons having wisdom, prohibiting (others) from Al-Fasad (disbelief, polytheism, and all kinds of crimes and sins) in the earth, (but there were none) - except a few of those whom We saved from among them! Those who did wrong pursued the enjoyment of good things of (this worldly) life, and were Mujrimun (criminals, disbelievers in Allah, polytheists, sinners).

(34) And (remember) when Musa (Moses) said to his people: "Call to mind Allah's Favour to you, when He delivered you from Fir'aun's (Pharaoh) people who were afflicting you with horrible torment, and were slaughtering your sons and letting your women alive; and in it was a tremendous trial from your Lord."

(35) Verily, Allah enjoins Al-'Adl (i.e. justice and worshipping none but Allah Alone - Islamic Monotheism) and Al-Ihsan [i.e. to be patient in performing your duties to Allah, totally for Allah's sake and in accordance with the Sunnah (legal ways) of the Prophet صلى الله عليه وسلم in a perfect manner], and giving (help) to kith and kin (i.e. all that Allah has ordered you to give them e.g., wealth, visiting, looking after them, or any other kind of help), and forbids Al-Fahsha' (i.e all evil deeds, e.g. illegal sexual acts, disobedience of parents, polytheism, to tell lies, to give false witness, to kill a life without right), and Al-Munkar (i.e all that is prohibited by Islamic law: polytheism of every kind, disbelief and every kind of evil deeds), and Al-Baghy (i.e. all kinds of oppression). He admonishes you, that you may take heed.

(36) And indeed We gave Musa (Moses) nine clear signs. Ask then the Children of Israel, when he came to them, then Fir'aun (Pharaoh) said to him: "O Musa (Moses)! I think you are indeed bewitched."

(37) [Musa (Moses)] said: "Verily, you know that these signs have been sent down by none but the Lord of the heavens and the earth (as clear evidence i.e. proofs of Allah's Oneness and His Omnipotence.). And I think you are, indeed, O Fir'aun (Pharaoh) doomed to destruction (away from all good)!"

(38) Then they both proceeded, till they met a boy, and he (Khidr) killed him. Musa (Moses) said: "Have you killed an innocent person who had killed none? Verily, you have committed a thing Nukr (a great Munkar - prohibited, evil, dreadful thing)!"

(39) (Allah said) "O Zakariyya (Zachariah)! Verily, We give you the glad tidings of a son, whose name will be Yahya (John). We have given that name to none before (him)."

(40) (It was said to his son): "O Yahya (John)! Hold fast the Scripture [the Taurat (Torah)]." And We gave him wisdom while yet a child.
