أَوْفَىٰ

Appears 4 times in the Quran. (Root: وفي)
  1. Yea, whoever fulfills his promise and guards (against evil)-- then surely Allah loves those who guard (against evil).

  2. Surely Allah has bought of the believers their persons and their property for this, that they shall have the garden; they fight in Allah's way, so they slay and are slain; a promise which is binding on Him in the Taurat and the Injeel and the Quran; and who is more faithful to his covenant than Allah? Rejoice therefore in the pledge which you have made; and that is the mighty achievement.

  3. 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.

  4. Then shall he be rewarded for it with the fullest reward-
