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

(161) Verily, your Lord knows that you do stand (to pray at night) a little less than two thirds of the night, or half the night, or a third of the night, and also a party of those with you. And Allah measures the night and the day. He knows that you are unable to pray the whole night, so He has turned to you (in mercy). So, recite you of the Qur'an as much as may be easy for you. He knows that there will be some among you sick, others travelling through the land, seeking of Allah's Bounty, yet others fighting in Allah's Cause. So recite as much of the Qur'an as may be easy (for you), and perform As-Salat (Iqamat-as-Salat ) and give Zakat, and lend to Allah a goodly loan. And whatever good you send before you for yourselves (i.e. Nawafil non-obligatory acts of worship: prayers, charity, fasting, Hajj and 'Umrah), you will certainly find it with Allah, better and greater in reward. And seek Forgiveness of Allah. Verily, Allah is Oft-Forgiving, Most-Merciful .

(162) Does man think that he will be left neglected (without being punished or rewarded for the obligatory duties enjoined by his Lord Allah on him)?

(163) (Saying): "We feed you seeking Allah's Countenance only. We wish for no reward, nor thanks from you.

(164) (And it will be said to them): "Verily, this is a reward for you, and your endeavour has been accepted."

(165) Verily, thus We reward the Muhsinun (good-doers. See V.2:112).

(166) A reward from your Lord, an ample calculated gift (according to the best of their good deeds),

(167) Save those who believe and do righteous good deeds, for them is a reward that will never come to an end (i.e. Paradise).

(168) Save those who believe (in Islamic Monotheism) and do righteous deeds. Then they shall have a reward without end (Paradise).

(169) Their reward with their Lord is 'Adn (Eden) Paradise (Gardens of Eternity), underneath which rivers flow. They will abide therein forever, Allah will be pleased with them, and they with Him. That is for him who fears his Lord.

(170) Verily, that Day (i.e. the Day of Resurrection) their Lord will be Well-Acquainted with them (as to their deeds and will reward them for their deeds).
