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.

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

Only those are believers who believe in Allah and His Apostle, and when they are with him on a momentous affair they go not away until they have asked his permission; surely they who ask your permission are they who believe in Allah and His Apostle; so when they ask your permission for some affair of theirs, give permission to whom you please of them and ask forgiveness for them from Allah; surely Allah is Forgiving, Merciful.

So do not follow the unbelievers, and strive against them a mighty striving with it.

And if you should ask them who created them, they would certainly say: Allah. Whence are they then turned back? / Consider his cry: O my Lord! surely they are a people who do not believe.

These are they who are unbelievers, the wicked.
