fulfill the covenant of Allah
-
1 I fulfill the covenant of Allah so that he supports me.
Allah said ( interpretation of the meaning ) :
{ And Allāh had already taken a covenant from the Children of Israel, and We delegated from among them twelve leaders. And Allāh said, "I am with you. If you establish prayer and give zakāh and believe in My messengers and support them and loan Allāh a goodly loan,1 I will surely remove from you your misdeeds and admit you to gardens beneath which rivers flow. But whoever of you disbelieves after that has certainly strayed from the soundness of the way." }
