Say: Whoever is an enemy to Gabriel-for he brings down the (revelation) to thy heart by God's will, a confirmation of what went before, and guidance and glad tidings for those who believe,- (2:97)

If ye two turn in repentance to Him, your hearts are indeed so inclined; But if ye back up each other against him, truly God is his Protector, and Gabriel, and (every) righteous one among those who believe,- and furthermore, the angels - will back (him) up. (66:4)
