I heard Abu Abdillah, peace be upon him, say: Indeed, to Allah, Exalted and Glorious is He, there are creations which He created from His Light, and a mercy from His mercy to His mercy; they are the observing Eye of Allah, and His hearing Ear, and his Tongue that speaks with his creation by His permission, and His Guardians upon what He has sent down of Justification, Warning or Proof. Hence, by them Allah erases misdeeds, and by them He repels grievance, and by them He sends down mercy, and by them He brings life into a dead and makes dead a living, and by them He tests His creation, and by them He decides in His creation His decision. I said: May I be sacrificed for you, who are these? He said: The Successors.
