We did reveal to Moses the Book after We had destroyed the earlier generations, (to give) Insight to men, and guidance and Mercy, that they might receive admonition. 43 NOW [as for thee, O Muhammad,] thou wert not present on the sunset slope [of Mount Sinai] when We imposed the Law upon Moses, nor wert thou among those who witnessed [his times]: 44 We raised (many more) generations and prolonged their lives. You did not live with the people of Midian, nor recited to them Our revelations; but We kept on sending messengers. 45 And you (O Muhammad SAW) were not at the side of the Tur (Mount) when We did call, [it is said that Allah called the followers of Muhammad SAW, and they answered His Call, or that Allah called Musa (Moses)]. But (you are sent) as a mercy from your Lord, to give warning to a people to whom no warner had come before you, in order that they may remember or receive admonition. [Tafsir At-Tabari, Vol. 20, Page 81]. 46 If (We had) not (sent thee to the Quraish),- in case a calamity should seize them for (the deeds) that their hands have sent forth, they might say: "Our Lord! why didst Thou not sent us a messenger? We should then have followed Thy Signs and been amongst those who believe!" 47 But (now) when the truth has come to them from Us, they say: Why is he not given the like of what was given to Musa? What! did they not disbelieve in what Musa was given before? They say: Two magicians backing up each other; and they say: Surely we are unbelievers in all. 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 But if they do not hearken to this, know well that they only follow their lusts and who is in greater error than he who follows his lusts without any guidance from Allah? Allah does not guide those given to wrong-doing. 50
