Does it not guide the people who inherit the land from former people that We can punish them for their sins if We will? And seal up their hearts so that they would not be able to lend an ear to words of guidance? 100 (Muhammad), such were the stories of the people who lived in (different) towns in the past. We had sent Our Messengers to them with (certain) miracles but the people still did not believe in what they had rejected before. Such is how God seals the hearts of the unbelievers. 101 We did not find the covenant upheld by the majority of them, but We found most of them evildoers. 102 Then We sent, after them, Musa with Our signs unto Fir'awn and his chiefs, but they wronged them. Behold that wise was the end of the corrupters! 103 And Musa said: O Fir'awn! I am an apostle from the Lord of the worlds; 104 I must only speak what is true about God. I have brought you miracles from your Lord; therefore, let the children of Israel go free". 105 The Pharaoh asked Moses to show his miracles if he was telling the truth. 106 So he threw his rod, then lo! it was a clear serpent. 107 And he drew forth his hand, and lo, it was white to the beholders. 108
