And there came indeed to them their Messengers with clear proofs, but they were not such as to believe in that which they had rejected before. Thus Allah does seal up the hearts of the disbelievers (from each and every kind of religious guidance). 101 We found no (loyalty to any) covenant in most of them.

Verily, I am an apostle from the Sustainer of all the worlds, 104 duty-bound to say nothing about God but the truth, and I have brought you a clear sign from your Lord. Let the Children of Israel go with me." 105 He said: If you have come with a sign, then bring it, if you are of the truthful ones. 106 Thereupon [Moses] threw down his staff, and lo! it was a serpent, plainly visible; 107 And he drew forth his hand, and behold, it looked white to those who beheld it. 108
