The word(s) "fulfills" appears 2 time(s) in 2 verse(s) in Quran in Saheeh International translation.

(1) But yes, whoever fulfills his commitment and fears Allah - then indeed, Allah loves those who fear Him.

(2) Indeed, those who pledge allegiance to you, [O Muhammad] - they are actually pledging allegiance to Allah. The hand of Allah is over their hands. So he who breaks his word only breaks it to the detriment of himself. And he who fulfills that which he has promised Allah - He will give him a great reward.
