Appears 2 times in the Quran. (Root: عهد)
  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.
