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 (O Muhammad), you were then not on the western side when We bestowed this commandment (of Law), and you were not among its witnesses. 44 Thereafter We raised up many a generation and a long time passed. You were then not even present among the people of Midian to rehearse Our verses to them. But it is We Who are sending news about that. 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 And if (We had) not (sent you to the people of Makkah) in case a calamity should seize them for (the deeds) that their hands have sent forth, they should have said: "Our Lord! Why did You not send us a Messenger? We should then have followed Your Ayat (Verses of the Quran) and should have been among 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 Say (to them, O Muhammad SAW): "Then bring a Book from Allah, which is a better guide than these two [the Taurat (Torah) and the Quran], that I may follow it, if you are truthful." 49 Then if they do not answer thee, know that they are only following their caprices; and who is further astray than he who follows his caprice without guidance from God? Surely God guides not the people of the evildoers. 50
