66:4If you repent to God, then your hearts have listened. But if you band together against him, then God is his Ally, as is Gabriel, and the righteous believers. In addition, the angels will assist him.

66:6O you who believe! Protect yourselves and your families from a Fire, whose fuel is people and stones. Over it are angels, fierce and powerful. They never disobey God in anything He commands them, and they carry out whatever they are commanded.
