The word(s) "oh" appears 111 time(s) in 99 verse(s) in Quran in Abdullah Yusuf Ali translation.

(31) Moses prayed: "Our Lord! Thou hast indeed bestowed on Pharaoh and his chiefs splendour and wealth in the life of the present, and so, Our Lord, they mislead (men) from Thy Path. Deface, our Lord, the features of their wealth, and send hardness to their hearts, so they will not believe until they see the grievous penalty."

(32) We took the Children of Israel across the sea: Pharaoh and his hosts followed them in insolence and spite. At length, when overwhelmed with the flood, he said: "I believe that there is no god except Him Whom the Children of Israel believe in: I am of those who submit (to Allah in Islam)."

(33) Unto Pharaoh and his chiefs: but they followed the command of Pharaoh and the command of Pharaoh was no right (guide).

(34) Why were there not, among the generations before you, persons possessed of balanced good sense, prohibiting (men) from mischief in the earth - except a few among them whom We saved (from harm)? But the wrong-doers pursued the enjoyment of the good things of life which were given them, and persisted in sin.

(35) Remember! Moses said to his people: "Call to mind the favour of Allah to you when He delivered you from the people of Pharaoh: they set you hard tasks and punishments, slaughtered your sons, and let your women-folk live: therein was a tremendous trial from your Lord."

(36) The worshippers of false gods say: "If Allah had so willed, we should not have worshipped aught but Him - neither we nor our fathers,- nor should we have prescribed prohibitions other than His." So did those who went before them. But what is the mission of messengers but to preach the Clear Message?

(37) To the Jews We prohibited such things as We have mentioned to thee before: We did them no wrong, but they were used to doing wrong to themselves.

(38) To Moses We did give Nine Clear Signs: As the Children of Israel: when he came to them, Pharaoh said to him: "O Moses! I consider thee, indeed, to have been worked upon by sorcery!

(39) Moses said, "Thou knowest well that these things have been sent down by none but the Lord of the heavens and the earth as eye-opening evidence: and I consider thee indeed, O Pharaoh, to be one doomed to destruction!"

(40) "Go thou to Pharaoh, for he has indeed transgressed all bounds."
