The word(s) "reward" appears 172 time(s) in 155 verse(s) in Quran in Abdullah Yusuf Ali translation.

(41) And know ye that your possessions and your progeny are but a trial; and that it is Allah with Whom lies your highest reward.

(42) They will dwell therein for ever. Verily in Allah's presence is a reward, the greatest (of all).

(43) But Allah did pour His calm on the Messenger and on the Believers, and sent down forces which ye saw not: He punished the Unbelievers; thus doth He reward those without Faith.

(44) It was not fitting for the people of Medina and the Bedouin Arabs of the neighbourhood, to refuse to follow Allah's Messenger, nor to prefer their own lives to his: because nothing could they suffer or do, but was reckoned to their credit as a deed of righteousness,- whether they suffered thirst, or fatigue, or hunger, in the cause of Allah, or trod paths to raise the ire of the Unbelievers, or received any injury whatever from an enemy: for Allah suffereth not the reward to be lost of those who do good;-

(45) Nor could they spend anything (for the cause) - small or great- nor cut across a valley, but the deed is inscribed to their credit: that Allah may requite their deed with the best (possible reward).

(46) To Him will be your return- of all of you. The promise of Allah is true and sure. It is He Who beginneth the process of creation, and repeateth it, that He may reward with justice those who believe and work righteousness; but those who reject Him will have draughts of boiling fluids, and a penalty grievous, because they did reject Him.

(47) To those who do right is a goodly (reward)- Yea, more (than in measure)! No darkness nor shame shall cover their faces! they are companions of the garden; they will abide therein (for aye)!

(48) But those who have earned evil will have a reward of like evil: ignominy will cover their (faces): No defender will they have from (the wrath of) Allah: Their faces will be covered, as it were, with pieces from the depth of the darkness of night: they are companions of the Fire: they will abide therein (for aye)!

(49) "But if ye turn back, (consider): no reward have I asked of you: my reward is only due from Allah, and I have been commanded to be of those who submit to Allah's will (in Islam)."

(50) Not so do those who show patience and constancy, and work righteousness; for them is forgiveness (of sins) and a great reward.
