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.

Certainly We sent Our messengers with clear arguments, and sent down with them the Book and the balance that men may conduct themselves with equity; and We have made the iron, wherein is great violence and advantages to men, and that Allah may know who helps Him and His messengers in the secret; surely Allah is Strong, Mighty.
