Allah bears witness that there is no god but He, and (so do) the angels and those possessed of knowledge, maintaining His creation with justice; there is no god but He, the Mighty, the Wise.

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.

Surely We revealed the Taurat in which was guidance and light; with it the prophets who submitted themselves (to Allah) judged (matters) for those who were Jews, and the masters of Divine knowledge and the doctors, because they were required to guard (part) of the Book of Allah, and they were witnesses thereof; therefore fear not the people and fear Me, and do not take a small price for My communications; and whoever did not judge by what Allah revealed, those are they that are the unbelievers.

Say: O Allah! Originator of the heavens and the earth, Knower of the unseen and the seen! Thou (only) judgest between Thy servants as to that wherein they differ.
