And We have put a seal upon their hearts, so that they hearken not. 100 Such were the townships. We relate some tidings of them unto thee (Muhammad). Their messengers verily came unto them with clear proofs (of Allah's Sovereignty), but they could not believe because they had before denied. Thus doth Allah print upon the hearts of disbelievers (that they hear not). 101 We did not find many of them faithful to their promises, and found many of them disobedient. 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 Incumbent it is upon me that I speak naught respecting Allah save the truth; surely I have brought you an evidence from your Lord; wherefore let then go with me the Children of Isra'il. 105 Pharaoh said: if you have brought a sign, then bring it forth if you are truthful.' 106 So he cast his staff; and behold, it was a serpent manifest. 107 Then he uncovered his hand and it appeared sheer white to the onlookers. 108
