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 Those cities - We relate to you, [O Muhammad], some of their news. And certainly did their messengers come to them with clear proofs, but they were not to believe in that which they had denied before. Thus does Allah seal over the hearts of the disbelievers. 101 And We did not find for most of them any covenant; but indeed, We found most of them defiantly disobedient. 102 Then after them We sent Musa (Moses) with Our Signs to Fir'aun (Pharaoh) and his chiefs, but they wrongfully rejected them. So see how was the end of the Mufsidun (mischief-makers, corrupts, etc.). 103 Moses said: "O Pharaoh, I have been sent by the Lord of all 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 He answered: 'If you have come with a sign, show it to us if you are of the truthful' 106 Thereupon Moses threw his rod, and suddenly it was a veritable serpent. 107 and he drew forth his hand, and it appeared [shining] white to the beholders. 108
