If what Fir`awn claims is true, that he is your lord and your god, then let him turn things around so that the heavenly bodies set in the east and rise in the west.' This is similar to the Ayah,

الذى حاج إبرهيم فى ربه أن آته الله الملك إذ قال إبرهيم ربي الذى يحى ويميت قال أنا أحى وأميت قال إبرهيم فٳن الله يٲتى بالشمس من المشرق فٲت بها من المغرب

who disputed with Ibrahim about his Lord, because Allah had given him the kingdom! When Ibrahim said: "My Lord is He Who gives life and causes death.'' He said, "I give life and cause death.'' Ibrahim said, "Verily, Allah brings the sun from the east. So cause it to rise from the west.'' (2:258) So when Fir`awn was defeated in debate, he resorted to the use of his force and power, believing that this would be effective in dealing with Musa, peace be upon him, so he said, as Allah tells us:
