To Him is your return, of all (of you); the promise of Allah (made) in truth; surely He begins the creation in the first mstance, then He reproduces it, that He may with justice recompense those who believe and do good; and (as for) those who disbelieve, they shall have a drink of hot water and painful punishment because they disbelieved.

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.
