The word(s) "promise" appears 137 time(s) in 117 verse(s) in Quran in Mohsin Khan translation.

(51) Musa (Moses) said: "Then go away! And verily, your (punishment) in this life will be that you will say: "Touch me not (i.e. you will live alone exiled away from mankind); and verily (for a future torment), you have a promise that will not fail. And look at your ilah (god) to which you have been devoted. We will certainly burn it, and scatter its particles in the sea."

(52) Verily, you have (a promise from Us) that you will never be hungry therein nor naked.

(53) Then We fulfilled to them the promise. So We saved them and those whom We willed, but We destroyed Al-Musrifun (i.e. disbelievers in Allah, in His Messengers, extravagants, transgressors of Allah's limits by committing crimes, oppressions, polytheism and sins).

(54) And they say: "When will this promise (come to pass), if you are truthful."

(55) And the true promise (Day of Resurrection) shall draw near (of fulfillment). Then (when mankind is resurrected from their graves), you shall see the eyes of the disbelievers fixedly staring in horror. (They will say): "Woe to us! We were indeed heedless of this - nay, but we were Zalimun (polytheists and wrong-doers)."

(56) The greatest terror (on the Day of Resurrection) will not grieve them, and the angels will meet them, (with the greeting): "This is your Day which you were promised."

(57) And (remember) the Day when We shall roll up the heaven like a scroll rolled up for books. As We began the first creation, We shall repeat it. (It is) a promise binding upon Us. Truly, We shall do it.

(58) But if they (disbelievers, idolaters, Jews, Christians, polytheists) turn away (from Islamic Monotheism) say (to them O Muhammad صلى الله عليه وسلم): "I give you a notice (of war as) to be known to us all alike. And I know not whether that which you are promised (i.e. the torment or the Day of Resurrection) is near or far. "

(59) And they ask you to hasten on the torment! And Allah fails not His promise. And verily, a day with your Lord is as a thousand years of what you reckon.

(60) And when Our Clear Verses are recited to them, you will notice a denial on the faces of the disbelievers! They are nearly ready to attack with violence those who recite Our Verses to them. Say: "Shall I tell you of something worse than that? The Fire (of Hell) which Allah has promised to those who disbelieved, and worst indeed is that destination!"
