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 were the towns whose story We relate unto you (O Muhammad SAW). And there came indeed to them their Messengers with clear proofs, but they were not such as to believe in that which they had rejected before. Thus Allah does seal up the hearts of the disbelievers (from each and every kind of religious guidance). 101 Most of them We found not men (true) to their covenant: but most of them We found rebellious and 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: 'Pharaoh, I am a Messenger 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 He said: if thou hast brought a sign, forth with it then, if thou art of the truth-tellers. 106 So he cast his staff; and behold, it was a serpent manifest. 107 And putting his hand in his bosom, withdrew it – so it shone brightly before the beholders. 108
