They did not hold Allah in due esteem when they said, “Allah has not sent down anything to a human being.” Say, “Who has sent down the Book brought by Mūsā as a light and a guidance for people, which you keep in various sheets (some of which) you disclose, and a lot of which you conceal, and (by which) you were taught what you did not know, neither you nor your fathers?” Say, “Allah.” Then leave them to play with whatever they indulge in.
This is indeed a Blessed Book We have sent down, confirming what was (revealed) before it, so that you may warn the town which is the Mother of All Towns, (i.e. Makkah) and those around it. Those who believe in the Hereafter believe in it, and they take due care of their prayers.
Who is more unjust than the one who fabricates a lie against Allah or says, “Revelation has been sent to me”, whereas no revelation has been sent to him, and the one who says, “I would produce the like of what Allah has revealed.” If only you could witness when the unjust are in the throes of death, and the angels stretch their hands (and say), “Out with your souls. Today, you shall have your punishment, a punishment of humiliation, because you have been saying about Allah what is not true, and have been showing arrogance against His verses.”
You have come to Us all alone, just as We had first created you, and you have left behind you what We had bestowed on you, and We do not see your intercessors with you - those whom you claimed to be (Our) partners in (managing) your matters. In fact, all ties between you are now severed, and all that you presumed has totally failed you.
