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

(41) Know they not that Allah knoweth both their secret and the thought that they confide, and that Allah is the Knower of Things Hidden?

(42) They will make excuse to you (Muslims) when ye return unto them. Say: Make no excuse, for we shall not believe you. Allah hath told us tidings of you. Allah and His messenger will see your conduct, and then ye will be brought back unto Him Who knoweth the Invisible as well as the Visible, and He will tell you what ye used to do.

(43) And say (unto them): Act! Allah will behold your actions, and (so will) His messenger and the believers, and ye will be brought back to the Knower of the Invisible and the Visible, and He will tell you what ye used to do.

(44) Lo! Allah hath bought from the believers their lives and their wealth because the Garden will be theirs: they shall fight in the way of Allah and shall slay and be slain. It is a promise which is binding on Him in the Torah and the Gospel and the Qur'an. Who fulfilleth His covenant better than Allah? Rejoice then in your bargain that ye have made, for that is the supreme triumph.

(45) And to the three also (did He turn in mercy) who were left behind, when the earth, vast as it is, was straitened for them, and their own souls were straitened for them till they bethought them that there is no refuge from Allah save toward Him. Then turned He unto them in mercy that they (too) might turn (repentant unto Him). Lo! Allah! He is the Relenting, the Merciful.

(46) Say: Have ye thought: When His doom cometh unto you as a raid by night, or in the (busy) day; what is there of it that the guilty ones desire to hasten?

(47) Then, after him, We sent messengers unto their folk, and they brought them clear proofs. But they were not ready to believe in that which they before denied. Thus print We on the hearts of the transgressors.

(48) And when they had cast, Moses said: That which ye have brought is magic. Lo! Allah will make it vain. Lo! Allah upholdeth not the work of mischief-makers.

(49) And We brought the Children of Israel across the sea, and Pharaoh with his hosts pursued them in rebellion and transgression, till, when the (fate of) drowning overtook him, he exclaimed: I believe that there is no Allah save Him in Whom the Children of Israel believe, and I am of those who surrender (unto Him).

(50) Lo! now they fold up their breasts that they may hide (their thoughts) from Him. At the very moment when they cover themselves with their clothing, Allah knoweth that which they keep hidden and that which they proclaim. Lo! He is Aware of what is in the breasts (of men).
