Has it not become clear to those who inherited the earth after its [previous] people that if We willed, We could afflict them for their sins? But We seal over their hearts so they do not hear. 100 Those cities We relate to thee tidings of; their Messengers came to them with the clear signs, but they were not the ones to believe in that they had cried lies before; so God seals the hearts of the unbelievers. 101 We did not find many of them faithful to their promises, and found many of them disobedient. 102 Then after them, We sent Moosa with our signs to Firaun and his court members, but they did injustice to those signs; therefore see what sort of fate befell the mischievous! 103 Moses said, "Pharaoh, I am a messenger from the Lord of the Universe, 104 "Proper it is for me that I say nothing concerning Allah but the truth. Indeed I have come unto you from your Lord with a clear proof. So let the Children of Israel depart along with me." 105 Said [Pharaoh]: "If thou hast come with a sign, produce it - if thou art a man of truth!" 106 So Moses threw down his staff and suddenly it turned into a real serpent. 107 Then he uncovered his hand and it appeared sheer white to the onlookers. 108
