And when Allah made a covenant through the prophets: Certainly what I have given you of Book and wisdom-- then an messenger comes to you verifying that which is with you, you must believe in him, and you must aid him. He said: Do you affirm and accept My compact in this (matter)? They said: We do affirm. He said: Then bear witness, and I (too) am of the bearers of witness with you.

One who had the knowledge of the Book said: I will bring it to you in the twinkling of an eye. Then when he saw it settled beside him, he said: This is of the grace of my Lord that He may try me whether I am grateful or ungrateful; and whoever is grateful, he is grateful only for his own soul, and whoever is ungrateful, then surely my Lord is Self-sufficient, Honored.
