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

(31) And certainly We have brought them a Book which We have made clear with knowledge, a guidance and a mercy for a people who believe.

(32) Do they wait for aught but its final sequel? On the day when its final sequel comes about, those who neglected it before will say: Indeed the apostles of our Lord brought the truth; are there for us then any intercessors so that they should intercede on our behalf? Or could we be sent back so that we should do (deeds) other than those which we did? Indeed they have lost their souls and that which they forged has gone away from them.

(33) And certainly We overtook Firon's people with droughts and diminution of fruits that they may be mindful.

(34) And We made the people who were deemed weak to inherit the eastern lands and the western ones which We had blessed; and the good word of your Lord was fulfilled in the children of Israel because they bore up (sufferings) patiently; and We utterly destroyed what Firon and his people had wrought and what they built.

(35) (As to) these, surely that about which they are shall be brought to naught and that which they do is vain.

(36) And when We shook the mountain over them as if it were a covering overhead, and they thought that it was going to fall down upon them: Take hold of what We have given you with firmness, and be mindful of what is in it, so that you may guard (against evil).

(37) And when your Lord brought forth from the children of Adam, from their backs, their descendants, and made them bear witness against their own souls: Am I not your Lord? They said: Yes! we bear witness. Lest you should say on the day of resurrection: Surely we were heedless of this.

(38) When you sought aid from your Lord, so He answered you: I will assist you with a thousand of the angels following one another.

(39) It is not fit for a prophet that he should take captives unless he has fought and triumphed in the land; you desire the frail goods of this world, while Allah desires (for you) the hereafter; and Allah is Mighty, Wise.

(40) Certainly they sought (to sow) dissension before, and they meditated plots against you until the truth came, and Allah's commandment prevailed although they were averse (from it).
