After We had destroyed the earlier generations, We gave Moses the Book to give men insight, and as guidance and a blessing for people, so that they might take heed. 43 Thou wast not upon the western side when We decreed to Moses the commandment, nor wast thou of those witnessing; 44 nay, but [between them and thee] We brought into being [many] generations, and long was their span of life. And neither didst thou dwell among the people of Madyan, conveying Our messages unto them: nay, but We have [always] been sending [Our message-bearers unto man]. 45 And you were not at the side of the mount when We called [Moses] but [were sent] as a mercy from your Lord to warn a people to whom no warner had come before you that they might be reminded. 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 (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 Say: Then bring some (other) book from Allah which is a better guide than both of them, (that) I may follow it, if you are truthful. 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
