Has it, then, not become obvious unto those who have inherited the earth in the wake of former generations that, if We so willed, We could smite them [too] by means of their sins, sealing their hearts so that they cannot hear [the truth]? 100 These are the dwellings – the affairs of which We relate to you (Prophet Mohammed – peace and blessings be upon him); and indeed their (respective) Noble Messengers came to them with clear proofs; so they were not able to believe in what they had denied before; this is how Allah sets seals upon the hearts of disbelievers. 101 We did not find many among them keeping their promises. However, We did find many evil-doers among them. 102 Then We sent, after them, Musa with Our signs unto Fir'awn and his chiefs, but they wronged them. Behold that wise was the end of the corrupters! 103 Moses said: O Pharaoh! Lo! I am a messenger from the Lord of the Worlds, 104 Approved upon condition that I speak concerning Allah nothing but the truth. I come unto you (lords of Egypt) with a clear proof from your Lord. So let the Children of Israel go with me. 105 He said: if thou hast brought a sign, forth with it then, if thou art of the truth-tellers. 106 Then [Musa (Moses)] threw his stick and behold! it was a serpent, manifest! 107 And putting his hand in his bosom, withdrew it – so it shone brightly before the beholders. 108
