And they measure not the power of Allah its true measure when they say: Allah hath naught revealed unto a human being. Say (unto the Jews who speak thus): Who revealed the Book which Moses brought, a light and guidance for mankind, which ye have put on parchments which ye show, but ye hide much (thereof), and (by which) ye were taught that which ye knew not yourselves nor (did) your fathers (know it)? Say: Allah. Then leave them to their play of cavilling. 91 And this (the Quran) is a blessed Book which We have sent down, confirming (the revelations) which came before it, so that you may warn the Mother of Towns (i.e. Makkah) and all those around it. Those who believe in the Hereafter believe in (the Quran), and they are constant in guarding their Salat (prayers). 92 Who can be more unjust than he who places a lie on Allah and who says: 'Revelation has come to me' when in fact nothing was revealed to him, and who says: 'I will produce the like of what Allah has revealed?' If you could but see the wrongdoers in the agonies of death, and the angels stretching out their hands (saying): 'Yield up your souls! Today you will be recompensed with the chastisement of humiliation for the lie you spoke concerning Allah, and for you waxing proud against His signs.' 93 'Now you have come to Us one by one, as We created you upon the first time, and you have left what We conferred on you behind your backs. We do not see with you your intercessors, those you asserted to be associates in you; the bond between you is now broken; that which you ever asserted has now gone astray from you. 94
