If you help him not, Allah certainly helped 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 on him and strengthened him with hosts which you saw not, and made lowest the word of those who disbelieved. And the word of Allah, that is the uppermost. And Allah is Mighty, Wise.
