The word(s) "promise" appears 124 time(s) in 108 verse(s) in Quran in Abdullah Yusuf Ali translation.

(91) Muhammad is the messenger of Allah; and those who are with him are strong against Unbelievers, (but) compassionate amongst each other. Thou wilt see them bow and prostrate themselves (in prayer), seeking Grace from Allah and (His) Good Pleasure. On their faces are their marks, (being) the traces of their prostration. This is their similitude in the Taurat; and their similitude in the Gospel is: like a seed which sends forth its blade, then makes it strong; it then becomes thick, and it stands on its own stem, (filling) the sowers with wonder and delight. As a result, it fills the Unbelievers with rage at them. Allah has promised those among them who believe and do righteous deeds forgiveness, and a great Reward.

(92) (A voice will say:) "This is what was promised for you,- for every one who turned (to Allah) in sincere repentance, who kept (His Law),

(93) Verily that which ye are promised is true;

(94) And in heaven is your Sustenance, as (also) that which ye are promised.

(95) Woe, then, to the Unbelievers, on account of that Day of theirs which they have been promised!

(96) That He hath promised a Second Creation (Raising of the Dead);

(97) Nay, the Hour (of Judgment) is the time promised them (for their full recompense): And that Hour will be most grievous and most bitter.

(98) And what cause have ye why ye should not spend in the cause of Allah?- For to Allah belongs the heritage of the heavens and the earth. Not equal among you are those who spent (freely) and fought, before the Victory, (with those who did so later). Those are higher in rank than those who spent (freely) and fought afterwards. But to all has Allah promised a goodly (reward). And Allah is well acquainted with all that ye do.

(99) (Those without) will call out, "Were we not with you?" (The others) will reply, "True! but ye led yourselves into temptation; ye looked forward (to our ruin); ye doubted (Allah's promise); and (your false) desires deceived you; until there issued the Command of Allah. And the Deceiver deceived you in respect of Allah.

(100) They ask: When will this promise be (fulfilled)? - If ye are telling the truth.
