Let’s check with Aisha, the first, last and only witness:
Aisha said, “The Prophet died in my house on the day of my turn while he was leaning on my chest closer to my neck, and Allah made my saliva mix with his saliva.”
Aisha added, “AbdurRahman came with a Siwak and the Prophet was too weak to use it so I took it, chewed it and then (gave it to him and he) cleaned his teeth with it.”
Sahih al-Bukhari 3100
Whenever Allah’s Messenger became ill, he used to recite the Muawidhatan (i.e. the last two surahs of the Qur’an) and blow his breath over himself (after their recitation ) and rubbed his hands over his body. So when he was afflicted with his fatal illness. I started reciting the Muawidhatan and blowing my breath over him as he used to do and then I rubbed the hand of the Prophet over his body.
Sahih al-Bukhari 4439
Aisha said, “Allah’s Messenger in his fatal illness, used to ask, ‘Where will I be tomorrow? Where will I be tomorrow?”, seeking Aisha’s turn. His wives allowed him to stay wherever he wished. So he stayed at Aisha’s house till he expired while he was with her.”
Aisha added, “The Prophet expired on the day of my turn in my house and he was taken unto Allah while his head was against my chest and his saliva mixed with my saliva.”
Aisha added, “Abdur-Rahman bin Abu Bakr came in, carrying a Siwak he was cleaning his teeth with. Allah’s Messenger looked at it and I said to him, ‘O `Abdur Rahman! Give me this Siwak.’ So he gave it to me and I cut it, chewed it (it’s end) and gave it to Allah’s Messenger who cleaned his teeth with it while he was resting against my chest.”
Sahih al-Bukhari 4450
She said that when the Prophet had a complaint he would blow on himself, ejecting saliva, reciting the Mu’awwidhat (See n. 1, p, 197.), and wipe himself with his hand. She said, “When he suffered from the pain of which he died, I would blow on him ejecting saliva and recite the Mu’awwidhat as he did, and would take the Prophet’s hand to wipe him.”
Mishkat al-Masabih 1532
I heard Allah’s Messenger saying, “No prophet gets sick but he is given the choice to select either this world or the Hereafter.”
Aisha added: During his fatal illness, his voice became very husky and I heard him saying: “In the company of those whom is the Grace of Allah, of the prophets, the Siddiqin (those followers of the prophets who were first and foremost to believe in them), the martyrs and the pious.’ (4.69)
And from this I came to know that he has been given the option.
Sahih al-Bukhari 4586
There’s more hadith all with subtle changes.
From these hadiths, I suspect that Aisha kissed and suffocated Muhammad: “my saliva mix with his saliva”.
Muhammad was a false prophet, for a false god, Allah, for a false religion, Islam, without even a false book, the Koran.
