۞ Have they not travelled in the earth and seen how was the end of those who were before them? Mightier than these were they in strength-- and in fortifications in the land, but Allah destroyed them for their sins; and there was not for them any defender against Allah. 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 And certainly We sent Musa with Our communications and clear authority, 23 to Pharaoh, Haman and Korah. But they said, "A magician, a liar." 24 And when he brought them the Truth from Our presence, they said: Slay the sons of those who believe with him, and spare their women. But the plot of disbelievers is in naught but error. 25 And Pharaoh said: "Leave it to me to slay Moses - and let him invoke his [alleged] sustainer! Behold, I fear lest he cause you to change your religion, or lest he cause corruption to prevail in the land!" 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
