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 Those villages We narrate their news to you. Their Messengers came to them with clear proofs, yet they would not believe what they had belied before; as such Allah seals the hearts of the unbelievers. 101 We found most of them untrue to their covenants, indeed We found most of them to be defiant. 102 After those We sent forth Moses with Our signs to Pharaoh and his nobles, but they dealt with Our signs unjustly. Observe, then, what happened to the mischief-makers. 103 And Moses said: 'O Pharaoh! I am a Messenger from the Lord of the universe. 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 Pharaoh said: if you have brought a sign, then bring it forth if you are truthful.' 106 So Moses threw down his staff and suddenly it turned into a real serpent. 107 And he drew forth his hand, when lo: it was white unto the beholders. 108
