The word(s) "ought" appears 205 time(s) in 189 verse(s) in Quran in Mohsin Khan translation.

(161) Then he turned to his household, and brought out a roasted calf [as the property of Ibrahim (Abraham) was mainly cows].

(162) So We brought out from therein the believers.

(163) And they indeed sought to shame his guest (by asking to commit sodomy with them). So We blinded their eyes, (saying) "Then taste you My Torment and My Warnings."

(164) Then, if he (the dying person) be of the Muqarrabun (those brought near to Allah),

(165) And what is the matter with you that you spend not in the Cause of Allah? And to Allah belongs the heritage of the heavens and the earth. Not equal among you are those who spent and fought before the conquering (of Makkah, with those among you who did so later). Such are higher in degree than those who spent and fought afterwards. But to all Allah has promised the best (reward). And Allah is All-Aware of what you do.

(166) Indeed We have sent Our Messengers with clear proofs, and revealed with them the Scripture and the Balance (justice) that mankind may keep up justice. And We brought forth iron wherein is mighty power (in matters of war ), as well as many benefits for mankind, that Allah may test who it is that will help Him (His religion) and His Messengers in the unseen. Verily, Allah is All-Strong, All-Mighty.

(167) Then, We sent after them Our Messengers, and We sent 'Îsa (Jesus) - son of Maryam (Mary), and gave him the Injeel (Gospel). And We ordained in the hearts of those who followed him compassion and mercy. But the monasticism which they invented for themselves, We did not prescribe for them, but (they sought it) only to please Allah therewith, but they did not observe it with the right observance. So We gave those among them who believed their (due) reward; but many of them are Fasiqun (rebellious, disobedient to Allah).

(168) He it is Who drove out the disbelievers among the people of the Scripture (i.e. the Jews of the tribe of Banu An-Nadir) from their homes at the first gathering. You did not think that they would get out. And they thought that their fortresses would defend them from Allah! But Allah's (Torment) reached them from a place whereof they expected it not, and He cast terror into their hearts so that they destroyed their own dwellings with their own hands and the hands of the believers. Then take admonition, O you with eyes (to see).

(169) Allah does not forbid you to deal justly and kindly with those who fought not against you on account of religion nor drove you out of your homes. Verily, Allah loves those who deal with equity.

(170) It is only as regards those who fought against you on account of religion, and have driven you out of your homes, and helped to drive you out, that Allah forbids you to befriend them. And whosoever will befriend them, then such are the Zalimun (wrong-doers - those who disobey Allah).
