If you read the quran, you find the expression “allah and his messenger” occurring all over the place. It is like allah can’t do anything by himself without involving his messenger (aka muhammad) all the time. Allah is totally dependent on him. As a matter of fact, allah can’t even get you to paradise without you obeying muhammad. And what is the consequence for not obeying his messenger? You go to the hellfire.
These are the boundaries of Allah and whoever obeys Allah and his messenger, he will admit him to gardens, below them the rivers flow; they abide in it forever, and this is the great triumph. 14 And whoever will disobey Allah and his messenger and will transgress his boundaries, he will admit him into a fire to abide in it forever, and he will have a shameful torment. Sura 4:13,14
See it? You can’t JUST obey allah. You need to embrace the whole package – AND his messenger. This deifies muhammad by putting him on the same level as allah. Welcome to shirk-land! Allah is weak and needs his messenger to pull things off.
So let’s think here for a moment. If allah is the true god, he can’t make any mistakes. Following me so far? And since the quran and the hadiths are admitting that muhammad was just a sinful man , that means that even muhammad must have got it wrong sometimes.
Well, as a matter of fact, muhammad never got things wrong. This is where the abrogation kicks in to play. Every time muhammad is in trouble, allah comes to the rescue and clear things up by sending down “a better verse”.
This is how muhammad could have more than four wives, take more booty, marry his adopted son’s wife, commit adultery, and so on. His wife Aisha saw this pattern in muhammad’s life.

Islam is false. Allah is a fabricated god made up by a false prophet.
