They ask you concerning the new moon. Say: They are times appointed for (the benefit of) men, and (for) the pilgrimage; and it is not righteousness that you should enter the houses at their backs, but righteousness is this that one should guard (against evil); and go into the houses by their doors and be careful (of your duty) to Allah, that you may be successful.

Say: If men and jinn should combine together to bring the like of this Quran, they could not bring the like of it, though some of them were aiders of others.

But (now) when the truth has come to them from Us, they say: Why is he not given the like of what was given to Musa? What! did they not disbelieve in what Musa was given before? They say: Two magicians backing up each other; and they say: Surely we are unbelievers in all.
