The word(s) "ought" appears 183 time(s) in 176 verse(s) in Quran in Muhammad Pickthal translation.

(131) And a believing man of Pharaoh's family, who hid his faith, said: Would ye kill a man because he saith: My Lord is Allah, and hath brought you clear proofs from your Lord? If he is lying, then his lie is upon him; and if he is truthful, then some of that wherewith he threateneth you will strike you. Lo! Allah guideth not one who is a prodigal, a liar.

(132) And verily Joseph brought you of old clear proofs, yet ye ceased not to be in doubt concerning what he brought you till, when he died, ye said: Allah will not send any messenger after him. Thus Allah deceiveth him who is a prodigal, a doubter.

(133) Then have patience (O Muhammad). Lo! the promise of Allah is true. And whether we let thee see a part of that which We promise them, or (whether) We cause thee to die, still unto Us they will be brought back.

(134) And when their messengers brought them clear proofs (of Allah's Sovereignty) they exulted in the knowledge they (themselves) possessed. And that which they were wont to mock befell them.

(135) That, your thought which ye did think about your Lord, hath ruined you; and ye find yourselves (this day) among the lost.

(136) And verily, if We cause him to taste mercy after some hurt that hath touched him, he will say: This is my own; and I deem not that the Hour will ever rise, and if I am brought back to my Lord, I surely shall be better off with Him - But We verily shall tell those who disbelieve (all) that they did, and We verily shall make them taste hard punishment.

(137) And Who sendeth down water from the sky in (due) measure, and We revive a dead land therewith. Even so will ye be brought forth;

(138) But when he brought them Our tokens, behold! they laughed at them.

(139) Therein are brought round for them trays of gold and goblets, and therein is all that souls desire and eyes find sweet. And ye are immortal therein.

(140) We verily brought the Truth unto you, but ye were, most of you, averse to the Truth.
