Thus it is that Allah seals the hearts of those who deny the truth. 101 We did not find many among them keeping their promises. However, We did find many evil-doers among them. 102 AND AFTER those [early people] We sent Moses with Our messages unto Pharaoh and his great ones, and they wilfully rejected them: and behold what happened in the end to those spreaders of corruption! 103 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 Said Firaun, “If you have come with a sign, then present it if you are truthful!” 106 Thereupon Moses threw his rod, and suddenly it was a veritable serpent. 107 and he drew forth his hand, and it appeared [shining] white to the beholders. 108
