The word(s) "fulfills" appears 2 time(s) in 2 verse(s) in Quran in Muhammad Habib Shakir translation.

(1) Yea, whoever fulfills his promise and guards (against evil)-- then surely Allah loves those who guard (against evil).

(2) Surely those who swear allegiance to you do but swear allegiance to Allah; the hand of Allah is above their hands. Therefore whoever breaks (his faith), he breaks it only to the injury of his own soul, and whoever fulfills what he has covenanted with Allah, He will grant him a mighty reward.
