But We seal over their hearts so they do not hear. 100 These are the dwellings – the affairs of which We relate to you (Prophet Mohammed – peace and blessings be upon him); and indeed their (respective) Noble Messengers came to them with clear proofs; so they were not able to believe in what they had denied before; this is how Allah sets seals upon the hearts of disbelievers. 101 We did not find most of them true to their covenants; indeed We found most of them to be transgressors. 102 Then We sent after them Moses with Our signs to Pharaoh and his establishment, but they were unjust toward them. So see how was the end of the corrupters. 103 And Moses said, "O Pharaoh, I am a messenger from the Lord of the worlds 104 (I am) worthy of not saying anything about Allah except the truth: I have come to you indeed with clear proof from your Lord, therefore send with me the children of Israel 105 He said: "If you have brought a sign then display it, if what you say is true." 106 So Moses threw down his staff and suddenly it turned into a real serpent. 107 Then he uncovered his hand and it appeared sheer white to the onlookers. 108
