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.

And certainly We have explained for men in this Quran every kind of similitude, but most men do not consent to aught but denying.

And certainly We have set forth for men every kind of example in this Quran; and if you should bring them a communication, those who disbelieve would certainly say: You are naught but false claimants.
