Muhammed got poisoned
Muhammad’s death was attributed to a poisoning that had occurred four years earlier after the battle of Khaybar in 628 CE. Historian Stephen Shoemaker says that “Western scholarship has persistently dismissed this tradition as unhistorical; in particular, the four year interval between the attempted poisoning and Muhammad’s sudden, fatal illness renders the story highly unlikely.
To secure Muhammed’s earth you have to be mindful to people that will want to poison you to stop you advancing to circleism. We just plant rhubarb in our garden as a little bit of posion.
Allah says “now put your finger down your throat”
