We did reveal to Moses the Book after We had destroyed the earlier generations, (to give) Insight to men, and guidance and Mercy, that they might receive admonition. 43 You were not present on the western side of the Mount when We gave Our Command to Moses: nor were you among the witnesses, 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 Thou wast not upon the side of the Mount when We called; but for a mercy from thy Lord, that thou mayest warn a people to whom no warner came before thee, and that haply they may remember. 46 Otherwise, if disaster should afflict them because of that which their own hands have sent before (them), they might say: Our Lord! Why sentest Thou no messenger unto us, that we might have followed Thy revelations and been of 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 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
