Is it not plain to those who inherit the earth after its inhabitants that if We willed We could smite them for their sins and set a seal upon their hearts, so that they do not hear. 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 most of them We found not (true) to their covenant, but most of them We found indeed Fasiqun (rebellious, disobedient to Allah). 102 After those We sent forth Moses with Our signs to Pharaoh and his nobles, but they dealt with Our signs unjustly. Observe, then, what happened to the mischief-makers. 103 And Moses said, "O Pharaoh, I am a messenger from the Lord of the worlds 104 worthy to say nothing regarding God except the truth. I have brought a clear sign to you from your Lord; so send forth with me the Children of Israel.' 105 [Pharaoh] said, "If you come with a sign, then produce it, if you are telling the truth." 106 So Moses threw down his staff and suddenly it turned into a real serpent. 107 And he drew forth his hand, and behold, it looked white to those who beheld it. 108
