And We gave Moses the Book, after We had destroyed the former generations, to be reflections for people and a guidance, and a mercy in order that they might remember. 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 But We raised up (new) generations, and long were the ages that passed over them; but thou wast not a dweller among the people of Madyan, rehearsing Our Signs to them; but it is We Who send messengers (with inspiration). 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 Else, did an affliction visit them for that their own hands have forwarded then they might say, 'Our Lord, why didst Thou not send a Messenger to us that we might follow Thy signs and so be among the believers?' 47 Yet when the truth is come unto them from before Us, they say: wherefore hast he not been vouchsafed the like of that which was given unto Musa? Disbelieved they not in that which was given unto Musa aforetime? They say; two magics supporting each other. And they say: verily in all such things we are disbelievers. 48 Say: 'If what you say is true, bring down from Allah a Book that is a better guidance than both, I will follow it' 49 But if they hearken not to thee, know that they only follow their own lusts: and who is more astray than one who follow his own lusts, devoid of guidance from Allah? for Allah guides not people given to wrong-doing. 50
