The word(s) "works" appears 12 time(s) in 12 verse(s) in Quran in Mohsin Khan translation.

(11) "They are those who deny the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) of their Lord and the Meeting with Him (in the Hereafter). So their works are in vain, and on the Day of Resurrection, We shall assign no weight for them.

(12) And he who works deeds of righteousness, while he is a believer (in Islamic Monotheism), then he will have no fear of injustice, nor of any curtailment (of his reward).
