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

(141) (The followers of the misleaders will say): "Nay, you (too)! No welcome for you! It is you (misleaders) who brought this upon us (because you misled us in the world), so evil is this place to stay in!"

(142) They will say: "Our Lord! Whoever brought this upon us, add to him a double torment in the Fire!"

(143) And he (Muhammad صلى الله عليه وسلم) who has brought the truth (this Qur'an and Islamic Monotheism) and (those who) believed therein (i.e. the true believers of Islamic Monotheism), those are Al-Muttaqun (the pious - See V.2:2).

(144) Say: "To Allah belongs all intercession. His is the Sovereignty of the heavens and the earth. Then to Him you shall be brought back."

(145) And the earth will shine with the light of its Lord (Allah, when He will come to judge among men): and the Book will be placed (open); and the Prophets and the witnesses will be brought forward; and it will be judged between them with truth, and they will not be wronged.

(146) Then, when he brought them the Truth from Us, they said: "Kill the sons of those who believe with him and let their women live"; but the plots of disbelievers are nothing but in vain!

(147) And you have not been hiding yourselves (in the world), lest your ears, and your eyes, and your skins should testify against you; but you thought that Allah knew not much of what you were doing.

(148) And that thought of yours which you thought about your Lord, has brought you to destruction; and you have become (this Day) of those utterly lost!

(149) And truly, if We give him a taste of mercy from Us, after some adversity (severe poverty or disease, etc.) has touched him, he is sure to say: "This is due to my (merit); I think not that the Hour will be established. But if I am brought back to my Lord, surely, there will be for me the best (wealth) with Him. Then, We verily, will show to the disbelievers what they have done, and We shall make them taste a severe torment.

(150) And thus We have revealed to you (O Muhammad صلى الله عليه و سلم) a Qur'an in Arabic that you may warn the Mother of the Towns (Makkah) and all around it, and warn (them) of the Day of Assembling of which there is no doubt: when a party will be in Paradise (those who believed in Allah and followed what Allah's Messenger صلى الله عليه و سلم brought them) and a party in the blazing Fire (Hell) (those who disbelieved in Allah and followed not what Allah's Messenger صلى الله عليه و سلم brought them).
