۞ 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 miracles and clear authority. 23 to Pharaoh, Haman and Korah. But they said, "A magician, a liar." 24 When We sent him to them for a genuine purpose, they said, "Kill the sons of those who have believed in him but keep their women alive." The plots of the unbelievers can only result in failure. 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 Musa said: Surely I take refuge with my Lord and-- your Lord from every proud one who does not believe in the day of reckoning. 27
