That is because Allah is the Protector of those who believe, and because the unbelievers shall have no protector for them.

Allah indeed has sanctioned for you the expiation of your oaths and Allah is your Protector, and He is the Knowing the Wise.

And whatever alms you give or (whatever) vow you vow, surely Allah knows it; and the unjust shall have no helpers.

Announce to the hypocrites that they shall have a painful chastisement: / Those who take the unbelievers for guardians rather than believers. Do they seek honor from them? Then surely all honor is for Allah.

And Allah turned back the unbelievers in their rage; they did not obtain any advantage, and Allah sufficed the believers in fighting; and Allah is Strong, Mighty.

And (as for) those who believe in Allah and His apostles, these it is that are the truthful and the faithful ones in the sight of their Lord: they shall have their reward and their light, and (as for) those who disbelieve and reject Our communications, these are the inmates of the hell.
