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 Thou wast not upon the western side when We decreed to Moses the commandment, nor wast thou of those witnessing; 44 We raised (many more) generations and prolonged their lives. You did not live with the people of Midian, nor recited to them Our revelations; but We kept on sending messengers. 45 You were not present on the side of Mount Sinai when We called. And all this (knowledge that you are given) is by the grace of your Lord so that you may warn a people to whom no admonisher had come before you, that they may take heed; 46 And in case disaster comes upon them for what they have done themselves, they should say: "O Lord, why did You not send an apostle to us that we should have followed Your commands, and been with those who are believers;" 47 But when the Truth reached them from Us, they said: "Why was he not given that which was given to Moses?" But did they not reject before what had been given to Moses? They said: "Both are magic, each supporting the other!" And they said: "We deny each of these." 48 Say (unto them, O Muhammad): Then bring a scripture from the presence of Allah that giveth clearer guidance than these two (that) I may follow it, if ye are truthful. 49 If they cannot meet such a challenge, know that they are only following their (evil) desires. Who strays more than one who follows his desires without guidance from God? God does not guide the unjust people. 50
