After We had destroyed the earlier generations We gave Moses the Book as evidence for mankind, and a guidance and grace, so that they may remember. 43 And you were not on the western side when We revealed to Musa the commandment, and you were not among the witnesses; 44 But We brought forth generations, and prolonged unto them was life; nor wast thou a dweller among the people of Madyan, reciting unto them Our revelations; but it is We who were to send. 45 And neither wert thou present on the slope of Mount Sinai when We called out [to Moses]: but [thou, too, art sent] as an act of thy Sustainer's grace, to warn people to whom no warner has come before thee, so that they might bethink themselves [of Us]; 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 But when there came unto them the Truth from Our presence, they said: Why is he not given the like of what was given unto Moses? Did they not disbelieve in that which was given unto Moses of old? They say: Two magics that support each other; and they say: Lo! in both we are disbelievers. 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 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
