The word(s) "reward" appears 190 time(s) in 170 verse(s) in Quran in Mohsin Khan translation.

(151) And those who believe in (the Oneness of) Allah and His Messengers - they are the Siddiqun (i.e. those followers of the Prophets who were first and foremost to believe in them), and the martyrs with their Lord, they shall have their reward and their light. But those who disbelieve (in the Oneness of Allah - Islamic Monotheism) and deny Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) - they shall be the dwellers of the blazing Fire.

(152) Then, We sent after them Our Messengers, and We sent 'Îsa (Jesus) - son of Maryam (Mary), and gave him the Injeel (Gospel). And We ordained in the hearts of those who followed him compassion and mercy. But the monasticism which they invented for themselves, We did not prescribe for them, but (they sought it) only to please Allah therewith, but they did not observe it with the right observance. So We gave those among them who believed their (due) reward; but many of them are Fasiqun (rebellious, disobedient to Allah).

(153) Your wealth and your children are only a trial, whereas Allah! With Him is a great reward (Paradise).

(154) If you lend Allah a goodly loan (i.e. spend in Allah's Cause), He will double it for you, and will forgive you. And Allah is Most Ready to appreciate and to reward, Most Forbearing,

(155) That is the Command of Allah, which He has sent down to you; and whosoever fears Allah and keeps his duty to Him, He will expiate from him his sins, and will enlarge his reward.

(156) Verily,, those who fear their Lord unseen (i.e. they do not see Him, nor His punishment in the Hereafter), theirs will be forgiveness and a great reward (i.e. Paradise).

(157) And Verily, for you (O Muhammad صلى الله عليه وسلم) will be an endless reward.

(158) We hope that our Lord will give us in exchange a better (garden) than this. Truly, we turn to our Lord (wishing for good that He may forgive our sins and reward us in the Hereafter).

(159) What is the matter with you, that [you fear not Allah (His punishment), and] you hope not for reward (from Allah or you believe not in His Oneness).

(160) 'And indeed when we heard the Guidance (this Qur'an), we believed therein (Islamic Monotheism), and whosoever believes in his Lord shall have no fear, either of a decrease in the reward of his good deeds or an increase in the punishment for his sins.
