Is it not clear to those who inherit the earth after its (former) residents that if We please We would afflict them on account of their faults and set a seal on their hearts so they would not hear. 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 We did not find the covenant upheld by the majority of them, but We found most of them evildoers. 102 After those We sent forth Moses with Our signs to Pharaoh and his assembly, but with it they harmed. Look at the end of the corrupters. 103 Moses said: O Pharaoh! Lo! I am a messenger from the Lord of the Worlds, 104 Approved upon condition that I speak concerning Allah nothing but the truth. I come unto you (lords of Egypt) with a clear proof from your Lord. So let the Children of Israel go with me. 105 Said [Pharaoh]: "If thou hast come with a sign, produce it - if thou art a man of truth!" 106 At this Moses threw down his staff, and lo, it became a live serpent. 107 And he drew forth his hand, and lo! it was white to the beholders. 108
