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

(81) And We brought them in unto Our mercy. Lo! they are among the righteous.

(82) O mankind! if ye are in doubt concerning the Resurrection, then lo! We have created you from dust, then from a drop of seed, then from a clot, then from a little lump of flesh shapely and shapeless, that We may make (it) clear for you. And We cause what We will to remain in the wombs for an appointed time, and afterward We bring you forth as infants, then (give you growth) that ye attain your full strength. And among you there is he who dieth (young), and among you there is he who is brought back to the most abject time of life, so that, after knowledge, he knoweth naught. And thou (Muhammad) seest the earth barren, but when We send down water thereon, it doth thrill and swell and put forth every lovely kind (of growth).

(83) Whoso is wont to think (through envy) that Allah will not give him (Muhammad) victory in the world and the Hereafter (and is enraged at the thought of his victory), let him stretch a rope up to the roof (of his dwelling), and let him hang himself. Then let him see whether his strategy dispelleth that whereat he rageth!.

(84) Therein are benefits for you for an appointed term; and afterward they are brought for sacrifice unto the ancient House.

(85) O mankind! A similitude is coined, so pay ye heed to it: Lo! those on whom ye call beside Allah will never create a fly though they combine together for the purpose. And if the fly took something from them, they could not rescue it from it. So weak are (both) the seeker and the sought!

(86) Then, after them, We brought forth another generation;

(87) Doth he promise you that you, when ye are dead and have become dust and bones, will (again) be brought forth?

(88) Then after them We brought forth other generations.

(89) And if the Truth had followed their desires, verily the heavens and the earth and whosoever is therein had been corrupted. Nay, We have brought them their Reminder, but from their Reminder they now turn away.

(90) Nay, but We have brought them the Truth, and lo! they are liars.
