The man “Pharaoh”, the ruler of Muhammad’s tribe, calls himself a god in Muhammad’s Koran:
[Pharaoh] said, “If you take a god other than me, I will surely place you among those imprisoned.”
Koran 26:29
And Pharaoh said, “O eminent ones, I have not known you to have a god other than me. Then ignite for me, O Hāmān, [a fire] upon the clay and make for me a tower that I may look at the God of Moses. And indeed, I do think he is among the liars.”
Koran 28:38
As you can see, Muhammad tells us that Pharaoh’s words are greater than Allah’s words. So obviously Pharaoh is a god (man) greater than Allah, thus showing Allah is merely an idol.
Why did Pharaoh call himself a “god”? Because he had the power of life and death over his tribe. If you were a member of his tribe, you’d live by his command and die by his command – his soldiers would execute you.
And Pharaoh said, “Let me kill Moses and let him call upon his Lord. Indeed, I fear that he will change your religion or that he will cause corruption in the land.”
Koran 40:26
And a believing man from the family of Pharaoh who concealed his faith said, “Do you kill a man [merely] because he says, ‘My Lord is Allāh’ while he has brought you clear proofs from your Lord? And if he should be lying, then upon him is [the consequence of] his lie; but if he should be truthful, there will strike you some of what he promises you. Indeed, Allāh does not guide one who is a transgressor and a liar.
Koran 40:28
27:48 And there were in the city nine family heads causing corruption in the land and not amending [its affairs].
49 They said, “Take a mutual oath by Allāh that we will kill him by night, he and his family. Then we will say to his executor, ‘We did not witness the destruction of his family, and indeed, we are truthful.'”
Koran 27:48-49
And a man came from the farthest end of the city, running. He said, “O Moses, indeed the eminent ones are conferring over you [intending] to kill you, so leave [the city]; indeed, I am to you of the sincere advisors.”
Koran 28:20
So why was Muhammad pretending to be Moses and disputing with Pharaoh the leader of his tribe? Because he was seeking to be ruler over his tribe, to be the new “pharaoh”, the new tyrant. This is what Muhammad achieved in his life, he invaded Mecca, took over, murdered those who opposed him, forced everyone into Islam and became their tyrant, the new Pharaoh.
Later, Muhammad was murdered – poisoned, for being a tyrant.
Muslims why do you worship a dead tyrant?
