Mohammad gave false statements about Allah
Within the Quran, it gives a test to confirm what Mohammad says is true. If Mohammad is lying, then he would have his aorta cut:
Quran 69:44-46
[44] And if he (Muhammad صلى الله عليه وسلم) had forged a false saying concerning Us (Allâh جل جلاله),
[45] We surely would have seized him by his right hand (or with power and might),
[46] And then We certainly would have cut off his life artery (aorta),
How did Mohammad die? A Jewish woman had poisoned his food to test if he actually was a prophet, and he died years later due to it. However, he specifically calls out that he feels like he is dying to his aorta being cut:
Sahih al-Bukhari 4428
The Prophet (ﷺ) in his ailment in which he died, used to say, "O `Aisha! I still feel the pain caused by the food I ate at Khaibar, and at this time, I feel as if my aorta is being cut from that poison."
We know that Mohammad was replacing verses within the Quran as this is actually called out in the Quran:
Quran 2:106
Any revelation We cause to be superseded or forgotten, We replace with something better or similar. Do you [Prophet] not know that God has power over everything?
Quran 16:101
When We substitute one revelation for another- and God knows best what He reveals- they say, ‘You are just making it up,’ but most of them have no knowledge.
We can take three facts from these verses:
- Allah reveals imperfect revelations
- When Allah does this, he'll fix it later and replace it with a better one. The Quran changes.
- Why would Allah do this? Only Allah knows
