And even if there were a Quran with which the mountains were made to pass away, or the earth were travelled over with it, or the dead were made to speak thereby; nay! the commandment is wholly Allah's, Have not yet those who believe known that if Allah please He would certainly guide all the people? And (as for) those who disbelieve, there will not cease to afflict them because of what they do a repelling calamity, or it will alight close by their abodes, until the promise of Allah comes about; surely Allah will not fail in (His) promise.

So when Musa had fulfilled the term, and he journeyed with his family, he perceived on this side of the mountain a fire. He said to his family: Wait, I have seen a fire, maybe I will bring to you from it some news or a brand of fire, so that you may warm yourselves.
