The word(s) "strives" appears 4 time(s) in 3 verse(s) in Quran in Mohsin Khan translation.

(1) And whoever desires the Hereafter and strives for it, with the necessary effort due for it (i.e. does righteous deeds of Allah's Obedience) while he is a believer (in the Oneness of Allah - Islamic Monotheism) - then such are the ones whose striving shall be appreciated, (thanked and rewarded by Allah).

(2) "Verily, the Hour is coming - and I am almost hiding it from Myself - that every person may be rewarded for that which he strives.

(3) And whosoever strives, he strives only for himself. Verily, Allah stands not in need of any of the 'Alamin (mankind, jinn, and all that exists).
