After destroying the people of the ancient towns We gave the Book to Moses to be a source of knowledge, a guidance, and mercy for mankind so that perhaps they would take heed. 43 (Prophet Muhammad) you were not on the western side (of the mountain) when We decreed the commandment to Moses, nor were you among those witnessing. 44 We raised generations who lived long. You did not live among the people of Midian, nor did you recite to them Our verses; but We were sending Messengers. 45 You were not present on the side of the Tor when We called. Yet as a mercy from your Lord to warn a nation to whom no warner has been sent before, in order that they remember 46 and may not say, if an affliction should befall them on account of their misdeeds: "Lord, if only You had sent us a messenger, we might have followed Your message and become believers." 47 So when the truth (Prophet Muhammad) came to them from Us, they said: 'Why is he not given the like of that which was given to Moses' But did they not also disbelieve in that which Moses was given before! They say (about Moses and Aaron): 'Two sorcerers supporting one another' And they said: 'We disbelieve both' 48 Say: "Then bring ye a Book from Allah, which is a better guide than either of them, that I may follow it! (do), if ye are truthful!" 49 But if they answer you not (i.e. do not believe in your doctrine of Islamic Monotheism, nor follow you), then know that they only follow their own lusts. And who is more astray than one who follows his own lusts, without guidance from Allah? Verily! Allah guides not the people who are Zalimun (wrong-doers, disobedient to Allah, and polytheists). 50
