The word(s) "ought" appears 193 time(s) in 181 verse(s) in Quran in Muhammad Habib Shakir translation.

(131) Say: Allah's is the intercession altogether; His is the kingdom of the heavens and the earth, then to Him you shall be brought back.

(132) And had those who are unjust all that is in the earth and the like of it with it, they would certainly offer it as ransom (to be saved) from the evil of the punishment on the day of resurrection; and what they never thought of shall become plain to them from Allah.

(133) And the evil (consequences) of what they wrought shall become plain to them, and the very thing they mocked at shall beset them.

(134) And the earth shall beam with the light of its Lord, and the Book shall be laid down, and the prophets and the witnesses shall be brought up, and judgment shall be given between them with justice, and they shall not be dealt with unjustly.

(135) So when he brought to them the truth from Us, they said: Slay the sons of those who believe with him and keep their women alive; and the struggle of the unbelievers will only come to a state of perdition.

(136) And a believing man of Firon's people who hid his faith said: What! will you slay a man because he says: My Lord is Allah, and indeed he has brought to you clear arguments from your Lord? And if he be a liar, on him will be his lie, and if he be truthful, there will befall you some of that which he threatens you (with); surely Allah does not guide him who is extravagant, a liar:

(137) And certainly Yusuf came to you before with clear arguments, but you ever remained in doubt as to what he brought; until when he died, you said: Allah will never raise an apostle after him. Thus does Allah cause him to err who is extravagant, a doubter

(138) The fire; they shall be brought before it (every) morning and evening and on the day when the hour shall come to pass: Make Firon's people enter the severest chastisement.

(139) And on the day that the enemies of Allah shall be brought together to the fire, then they shall be formed into groups.

(140) And they shall say to their skins: Why have you borne witness against us? They shall say: Allah Who makes everything speak has made us speak, and He created you at first, and to Him you shall be brought back.
