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 townships! We recount unto thee some tidings thereof. Assuredly there came unto them their apostles with evidences, but they were not such as to believe that which they had erst belied. Thus doth Allah put a seal upon the hearts of the infidels. 101 We did not find most of them true to their covenants; indeed We found most of them to be transgressors. 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 Moses said: "O 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 Pharaoh said: if you have brought a sign, then bring it forth if you are truthful.' 106 So Moses threw his staff, and suddenly it was a serpent, manifest. 107 Then he uncovered his hand and it appeared sheer white to the onlookers. 108
