After We had destroyed the earlier generations We bestowed the Book on Moses - a source of enlightenment for people and a guidance and mercy -- that they may take heed. 43 Thou wast not on the Western side when We decreed the Commission to Moses, nor wast thou a witness (of those events). 44 But We brought forth generations, and their lives dragged on for them. And thou wast not a dweller in Midian, reciting unto them Our revelations, but We kept sending (messengers to men). 45 And neither wert thou present on the slope of Mount Sinai when We called out [to Moses]: but [thou, too, art sent] as an act of thy Sustainer's grace, to warn people to whom no warner has come before thee, so that they might bethink themselves [of Us]; 46 And in case disaster comes upon them for what they have done themselves, they should say: "O Lord, why did You not send an apostle to us that we should have followed Your commands, and been with those who are believers;" 47 Yet when the truth came to them 'from Ourselves, they said, 'Why has he not been given the like' of that Moses was given?' But they, did they not disbelieve also in what Moses was given aforetime? They said, 'A pair of sorceries mutually supporting each other.' They said, 'We disbelieve both.' 48 Say to them, "Bring down from God a scripture that is a better guide than these two and I will follow it, if what you say be true." 49 Then, if they cannot give you an answer, know that they are only following their lusts. And who can be farther astray than he who follows his lust without any guidance from God? And certainly God does not guide an unjust people. 50
