Their Messengers came to them with clear proofs, yet they would not believe what they had belied before; as such Allah seals the hearts of the unbelievers. 101 We found no (loyalty to any) covenant in most of them. Nay, most of them We found wrong-doers. 102 After those We sent forth Moses with Our signs to Pharaoh and his assembly, but with it they harmed. Look at the end of the corrupters. 103 And Musa said: O Fir'awn! I am an apostle from the Lord of the worlds; 104 [Who is] obligated not to say about Allah except the truth. I have come to you with clear evidence from your Lord, so send with me the Children of Israel." 105 Said Firaun, “If you have come with a sign, then present it if you are truthful!” 106 So Moses threw his staff, and suddenly it was a serpent, manifest. 107 and he drew forth his hand, and lo! it appeared [shining] white to the beholders. 108
