Thus doth Allah seal up the hearts of those who reject faith. 101 We found no covenant in the most part of them; indeed, We found the most part of them ungodly. 102 After them We sent Moses with Our signs to Pharaoh and his chiefs. But they willfully rejected them.

Let the Children of Israel go with me." 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 And putting his hand in his bosom, withdrew it – so it shone brightly before the beholders. 108
