Or did not those who inherited the land after its owners, get enough guidance that if We will, We can afflict them with calamity for their sins? And We set seals upon their hearts so they do not hear. 100 Those were the towns whose story We relate unto you (O Muhammad SAW). 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 covenant in the most part of them; indeed, We found the most part of them ungodly. 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 "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 he, 'If thou hast brought a sign, produce it, if thou speakest truly.' 106 Thereupon [Moses] threw down his staff, and lo! it was a serpent, plainly visible; 107 Then he uncovered his hand and it appeared sheer white to the onlookers. 108
