They behaved in the same manner towards the Book that was given to Prophet Moses (peace be upon him). Therefore, O Muhammad (peace be upon him), do not be disheartened by their rejection of the Quran, though its teachings are simple and plain.

But this will happen in due course as previously ordained by Allah, for Allah does not make haste in passing judgment, though the people demand haste.
