Muhammad lies a lot in his Koran and these are often mistaken for prophecies. Allah speaks (in several separate stories) to Iblis, one of the many Jinn, whose native home is the Fire (Hell):
[Allāh] said, “Depart from it [i.e., Paradise], reproached and expelled. Whoever follows you among them – I will surely fill Hell with you, all together.”
Koran 7:18
Notice the difference in what “[Allah]” says.
38:84 [Allāh] said, “The truth [is My oath], and the truth I say – 85 [That] I will surely fill Hell with you and those of them that follow you all together.”
Koran 38:84-85
And worse, there’s another version of the story:
And those who disbelieve and deny Our signs – those will be companions of the Fire; they will abide therein eternally.”
Koran 2:39
And another:
15:42 Indeed, My servants – no authority will you have over them, except those who follow you of the deviators.
43 And indeed, Hell is the promised place for them all.
44 It has seven gates; for every gate is of them [i.e., Satan’s followers] a portion designated.”
Koran 15:42-44
If Allah is one, as many Muslims and Islam state, then Allah surely says things once, and once only. Then why does Allah say this differently? Which one is right? Obviously, all are wrong, they’re lies.
Fire isn’t much of a threat, because Jinn are made of fire, so Hell or Fire is their native home. It’s like police sending a tourist back home early because he’s misbehaved. This is more of a threat to those humans who follow Iblis, as they’re made of water and fire and water doesn’t really mix well.
But, how are we humans to know not to follow Iblis? Were we there with Iblis? You’d be right to think we weren’t there, but according to the Koran, all of us were there, and able to listen in. For more, see my article: Everyone is Born Muslim? As I show in that article, we’re not there with Allah and Iblis. So this is a false prophecy from the start. Also, humans don’t understand the Arabic that Muhammad spoke when he recited his Koran to his friends and enemies.
Here are Muhammad’s next two references to this “prophecy” or rather lies and threats:
Except whom your Lord has given mercy, and for that He created them.
But the word of your Lord is to be fulfilled that, “I will surely fill Hell with jinn and men all together.”
Koran 11:119
And if We had willed, We could have given every soul its guidance, but the word from Me will come into effect [that] “I will surely fill Hell with jinn and people all together.
Koran 32:13
These two verses aren’t the words of Allah; they’re from Muhammad talking about Allah’s supposed prophecy earlier, thus there’s no Qur’an, no written text on preserved tablets, no Allah.
As you can see, there are multiple versions of supposedly one prophecy, and all are wrong. Worse, 1400 years later, nothing has happened. Muhammad and his enemies are dust in the desert. None are in the Fire.
Muhammad was a false prophet, for a false god, Allah, for a false religion, Islam, without even a false book, the Koran.
