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

(71) When the youths sought refuge in the cave, they said: Our Lord! grant us mercy from Thee, and provide for us a right course in our affair.

(72) And they shall be brought before your Lord, standing in ranks: Now certainly you have come to Us as We created you at first. Nay, you thought that We had not appointed to you a time of the fulfillment of the promise.

(73) He said: This is what we sought for; so they returned retracing their footsteps.

(74) And says man: What! when I am dead shall I truly be brought forth alive?

(75) Saying: Put him into a chest, then cast it down into the river, then the river shall throw him on the shore; there shall take him up one who is an enemy to Me and enemy to him, and I cast down upon you love from Me, and that you might be brought up before My eyes;

(76) When your sister went and said: Shall I direct you to one who will take charge of him? So We brought you back to your mother, that her eye might be cooled and she should not grieve and you killed a man, then We delivered you from the grief, and We tried you with (a severe) trying. Then you stayed for years among the people of Madyan; then you came hither as ordained, O Musa.

(77) So go you both to him and say: Surely we are two apostles of your Lord; therefore send the children of Israel with us and do not torment them! Indeed we have brought to you a communication from your Lord, and peace is on him who follows the guidance;

(78) Who made the earth for you an expanse and made for you therein paths and sent down water from the cloud; then thereby We have brought forth many species of various herbs.

(79) And cast down what is in your right hand; it shall devour what they have wrought; they have wrought only the plan of a magician, and the magician shall not be successful wheresoever he may come from.

(80) So he brought forth for them a calf, a (mere) body, which had a mooing sound, so they said: This is your god and the god of Musa, but he forgot.
