And [then,] indeed, after We had destroyed those earlier generations [of sinners,] We vouchsafed unto Moses [Our] revelation as a means of insight for men, and as a guidance and grace, so that they might bethink themselves [of Us]. 43 You were not present on the western side of the Mount when We gave Our Command to Moses: nor were you among the witnesses, 44 But We brought forth generations, and prolonged unto them was life; nor wast thou a dweller among the people of Madyan, reciting unto them Our revelations; but it is We who were to send. 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 if not that a disaster should strike them for what their hands put forth [of sins] and they would say, "Our Lord, why did You not send us a messenger so we could have followed Your verses and been among the believers?"... 47 But when the truth (i.e. Muhammad SAW with his Message) has come to them from Us, they say: "Why is he not given the like of what was given to Musa (Moses)? Did they not disbelieve in that which was given to Musa (Moses) of old? They say: "Two kinds of magic [the Taurat (Torah) and the Quran] each helping the other!" And they say: "Verily! In both we are disbelievers." 48 Say: "Then bring a Book from God which gives better guidance than these so that I may follow it, if you speak the truth." 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
