Indeed there was a sign for you in the two hosts (which) met together in encounter; one party fighting in the way of Allah and the other unbelieving, whom they saw twice as many as themselves with the sight of the eye and Allah strengthens with His aid whom He pleases; most surely there is a lesson in this for those who have sight.

If you will not aid him, Allah certainly aided him when those who disbelieved expelled him, he being the second of the two, when they were both in the cave, when he said to his companion: Grieve not, surely Allah is with us. So Allah sent down His tranquillity upon him and strengthened him with hosts which you did not see, and made lowest the word of those who disbelieved; and the word of Allah, that is the highest; and Allah is Mighty, Wise.

O you who believe! be helpers (in the cause) of Allah, as~ Isa son of Marium said to (his) disciples: Who are my helpers in the cause of Allah? The disciples said: We are helpers (in the cause) of Allah. So a party of the children of Israel believed and another party disbelieved; then We aided those who believed against their enemy, and they became uppermost.
