The word(s) "fulfill" appears 21 time(s) in 21 verse(s) in Quran in Muhammad Habib Shakir translation.

(11) And fulfill the covenant of Allah when you have made a covenant, and do not break the oaths after making them fast, and you have indeed made Allah a surety for you; surely Allah knows what you do.

(12) And draw not near to the property of the orphan except in a goodly way till he attains his maturity and fulfill the promise; surely (every) promise shall be questioned about.

(13) And they say: Glory be to our Lord! most surely the promise of our Lord was to be fulfilled.

(14) And they shall be brought before your Lord, standing in ranks: Now certainly you have come to Us as We created you at first. Nay, you thought that We had not appointed to you a time of the fulfillment of the promise.

(15) He said: This shall be (an agreement) between me and you; whichever of the two terms I fulfill, there shall be no wrongdoing to me; and Allah is a witness of what we say.

(16) So when Musa had fulfilled the term, and he journeyed with his family, he perceived on this side of the mountain a fire. He said to his family: Wait, I have seen a fire, maybe I will bring to you from it some news or a brand of fire, so that you may warm yourselves.

(17) And they say: When will this promise be (fulfilled) if you are truthful?

(18) 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.

(19) And (of) Ibrahim who fulfilled (the commandments):

(20) The heaven shall rend asunder thereby; His promise is ever brought to fulfillment.
