۞ Have they not travelled on the earth that they could see what happened to those before them? They were greater in strength than they, and have left behind them traces on the earth. Yet they were seized by God for their sins, and had none to protect them against God. 21 That was because they disbelieved their Messengers when they came to them with clear signs, and so Allah seized them. Surely, He is Strong, and Stern in retribution. 22 We sent Moses with Our signs and clear authority 23 to Pharaoh, Haman and Korah; they said, 'A lying sorcerer!' 24 So when he brought to them the truth from Us, they said: Slay the sons of those who believe with him and keep their women alive; and the struggle of the unbelievers will only come to a state of perdition. 25 And Fir'awn said: let me alone, that I may slay Musa, and let him call upon his Lord. Verily I fear that he may change your religion or that he may cause to appear in the land corruption. 26 And Moses said, 'I take refuge in my Lord and your Lord from every man who is proud, and believes not in the Day of Reckoning.' 27
