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

(41) And We said to the Children of Israel after him: "Dwell in the land, then, when the final and the last promise comes near [i.e. the Day of Resurrection or the descent of Christ ['Îsa (Jesus), son of Maryam (Mary) عليهما السلام on the earth], We shall bring you altogether as mixed crowd (gathered out of various nations). (Tafsir Al-Qurtubi,).

(42) And they say: "Glory be to our Lord! Truly, the promise of our Lord must be fulfilled."

(43) And thus We made their case known (to the people), that they might know that the promise of Allah is true, and that there can be no doubt about the Hour. (Remember) when they (the people of the city) disputed among themselves about their case, they said: "Construct a building over them; their Lord knows best about them;" (then) those who won their point said (most probably the disbelievers): "We verily shall build a place of worship over them."

(44) (Dhul-Qarnain) said: "This is a mercy from my Lord, but when the promise of my Lord comes, He shall level it down to the ground. And the promise of my Lord is ever true."

(45) And mention in the Book (the Qur'an) Isma'il (Ishmael). Verily he was true to what he promised, and he was a Messenger, (and) a Prophet.

(46) (They will enter) 'Adn (Eden) Paradise (everlasting Gardens), which the Most Gracious (Allah) has promised to His slaves in the Unseen: Verily His promise must come to pass.

(47) Say (O Muhammad صلى الله عليه وسلم) whoever is in error, the Most Gracious (Allah) will extend (the rope) to him, until, when they see that which they were promised, either the torment or the Hour, they will come to know who is worst in position, and who is weaker in forces. [This is the answer to the question in Verse No.19:73]

(48) None shall have the power of intercession, but such a one as has received permission (or promise) from the Most Gracious (Allah).

(49) Then Musa (Moses) returned to his people in a state of anger and sorrow. He said: "O my people! Did not your Lord promise you a fair promise? Did then the promise seem to you long in coming? Or did you desire that wrath should descend from your Lord on you, that you broke your promise to me (i.e disbelieving in Allah and worshipping the calf)?"

(50) They said: "We broke not the promise to you, of our own will, but we were made to carry the weight of the ornaments of the [Fir'aun's (Pharaoh)] people, then we cast them (into the fire), and that was what As-Samiri suggested."
