And seal up their hearts so that they would not be able to lend an ear to words of guidance? 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 We did not find many of them faithful to their promises, and found many of them disobedient. 102 Then after them We sent Musa (Moses) with Our Signs to Fir'aun (Pharaoh) and his chiefs, but they wrongfully rejected them. So see how was the end of the Mufsidun (mischief-makers, corrupts, etc.). 103 Moses said, "Pharaoh, I am a messenger from the Lord of the Universe, 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 thou comest with a token, then produce it, if thou art of those who speak the truth. 106 So Moses threw his staff, and suddenly it was a serpent, manifest. 107 Then he drew out his hand and it was luminous to the onlookers. 108
