Is it not an indication to those who inherit the land after its people (who thus reaped the consequence of evil-doing) that, if We will, We can smite them for their sins and print upon their hearts so that they hear 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 did not find the covenant upheld by the majority of them, but We found most of them evildoers. 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 Moses said: "O Pharaoh, I have been sent by the Lord of all 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 he, 'If thou hast brought a sign, produce it, if thou speakest truly.' 106 Then he flung down his staff and lo! it was a serpent manifest; 107 And he drew forth his hand, when lo: it was white unto the beholders. 108
