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

(41) Do they not know that Allah knows their hidden thoughts and their secret counsels, and that Allah is the great Knower of the unseen things?

(42) They will excuse themselves to you when you go back to them. Say: Urge no excuse, by no means will we believe you; indeed Allah has informed us of matters relating to you; and now Allah and His Apostle will see your doings, then you shall be brought back to the Knower of the unseen and the seen, then He will inform you of what you did.

(43) And say: Work; so Allah will see your work and (so will) His Apostle and the believers; and you shall be brought back to the Knower of the unseen and the seen, then He will inform you of what you did.

(44) Surely Allah has bought of the believers their persons and their property for this, that they shall have the garden; they fight in Allah's way, so they slay and are slain; a promise which is binding on Him in the Taurat and the Injeel and the Quran; and who is more faithful to his covenant than Allah? Rejoice therefore in the pledge which you have made; and that is the mighty achievement.

(45) There shall every soul become acquainted with what it sent before, and they shall be brought back to Allah, their true Patron, and what they devised shall escape from them.

(46) He gives life and causes death, and to Him you shall be brought back.

(47) And what will be the thought of those who forge lies against Allah on the day of resurrection? Most surely Allah is the Lord of grace towards men, but most of them do not give thanks.

(48) So when they cast down, Musa said to them: What you have brought is deception; surely Allah will make it naught; surely Allah does not make the work of mischief-makers to thrive.

(49) These are they for whom there is nothing but fire in the hereafter, and what they wrought in it shall go for nothing, and vain is what they do.

(50) And who is more unjust than he who forges a lie against Allah? These shall be brought before their Lord, and the witnesses shall say: These are they who lied against their Lord. Now surely the curse of Allah is on the unjust.
