And We have put a seal upon their hearts, so that they hearken not. 100 Such were the townships. We relate some tidings of them unto thee (Muhammad). Their messengers verily came unto them with clear proofs (of Allah's Sovereignty), but they could not believe because they had before denied. Thus doth Allah print upon the hearts of disbelievers (that they hear not). 101 We found no (loyalty to any) covenant in most of them. Nay, most of them We found wrong-doers. 102 Then we raised after them Musa with Our communications to Firon and his chiefs, but they disbelieved in them; consider then what was the end of the mischief makers. 103 And Musa said: O Fir'awn! I am an apostle from the Lord of the worlds; 104 I must only speak what is true about God. I have brought you miracles from your Lord; therefore, let the children of Israel go free". 105 Said [Pharaoh]: "If thou hast come with a sign, produce it - if thou art a man of truth!" 106 He threw down his staff, and it was clearly a serpent. 107 And he drew forth his hand, and behold, it looked white to those who beheld it. 108
