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 (Muhammad), you were not present at the west bank to witness when We gave the commandments to Moses. 44 but We raised up generations, and long their lives continued. Neither wast thou a dweller among the Midianites, reciting to them Our signs; but We were sending Messengers. 45 Nor wast thou beside the Tur when We called; but thou art sent as a mercy from thy Lord, that thou mayest warn a people unto whom no warner came before thee, that haply they might be admonished. 46 And were it not that there should befall them a disaster for what their hands have sent before, then they should say: Our Lord! why didst Thou not send to us an apostle so that we should have followed Thy communications and been of the believers! 47 But when the Truth reached them from Us, they said: "Why was he not given that which was given to Moses?" But did they not reject before what had been given to Moses? They said: "Both are magic, each supporting the other!" And they said: "We deny each of these." 48 (Muhammad), tell them, "Bring a Book if you are able to, from God better in its guidance than the Torah and the Quran; I shall follow it". 49 If they do not answer you, know that they are only following their desires. And who is further astray than he who is led by his desires without guidance from Allah! Allah does not guide the harmdoers. 50
