It goes from bad to worse for Muhammad. Not only did he have to live under the constant terror and dread of his god he even had to undergo some rather humiliating circumstances:
Magic was worked on Allah's Apostle so that he used to think that he had sexual relations with his wives while he actually had not (Sufyan said: That is the hardest kind of magic as it has such an effect). Then one day he said, "O ‘Aisha do you know that Allah has instructed me concerning the matter I asked Him about? Two men came to me and one of them sat near my head and the other sat near my feet. The one near my head asked the other, ‘What is wrong with this man?’ The latter replied he is under the effect of magic. The first one asked, ‘Who has worked magic on him?’ The other replied, ‘Labid bin Al-A’sam, a man from Bani Zuraiq who was an ally of the Jews and was a hypocrite.’ The first one asked, ‘What material did he use?’ The other replied, ‘A comb and the hair stuck to it.’ The first one asked, ‘Where (is that)?’ The other replied, ‘In a skin of pollen of a male date palm tree kept under a stone in the well of Dharwan.’" So the Prophet went to that well and took out those things and said, "That was the well which was shown to me (in a dream). Its water looked like the infusion of Henna leaves and its date-palm trees looked like the heads of devils." The Prophet added, "Then that thing was taken out." I said (to the Prophet) "Why do you not treat yourself with Nashra?" He said, "Allah has cured me; I dislike to let evil spread among my people." (Sahih al-Bukhari, Volume 7, Book 71, Number 660)
According to specific sources the spell lasted a year:
I In commenting on this Suhayli asserts that the tradition is sound and is accepted by the traditionists. He found in the Jami’ of Mu‘ammar b. Rashad (a work which I cannot find mentioned by Brockelmann) the statement THAT THE SPELL LASTED A YEAR. He adds that the Mu‘tazila and Modernists rejected the tradition on the ground that prophets could not be bewitched otherwise they would commit sin and that would be contrary to the word of God ‘And God will protect thee from men’ (5.71). He finds the tradition unassailable. It is properly attested and intellectually acceptable. The prophets were not preserved from bodily afflictions in which category sorcery falls. (The Life of Muhammad, A Translation of Ibn Ishaq’s Sirat Rasul Allah, with introduction and notes by Alfred Guillaume [Oxford University Press, Karachi, Tenth Impression 1995), p. 240; bold and capital emphasis ours)
Moreover, Allah allowed Muhammad to endure a very painful death as a result of food poisoning:
Narrated Anas bin Malik:
A Jewess brought a poisoned (cooked) sheep for the Prophet who ate from it. She was brought to the Prophet and he was asked, "Shall we kill her?" He said, "No." I continued to see the effect of the poison on the palate of the mouth of Allah's Apostle. (Sahih al-Bukhari, Volume 3, Book 47, Number 786)
Narrated Ibn Abbas:
'Umar bin Al-Khattab used to let Ibn Abbas sit beside him, so 'AbdurRahman bin 'Auf said to 'Umar, "We have sons similar to him." 'Umar replied, "(I respect him) because of his status that you know." 'Umar then asked Ibn 'Abbas about the meaning of this Holy Verse:-- "When comes the help of Allah and the conquest of Mecca..." (110.1)
Ibn 'Abbas replied, "That indicated the death of Allah's Apostle which Allah informed him of." 'Umar said, "I do not understand of it except what you understand." Narrated 'Aisha: The Prophet 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." (Sahih al-Bukhari, Volume 5, Book 59, Number 713)
His condition became so severe that some of his own companions thought that Muhammad had become mentally ill, even delirious:
Narrated Said bin Jubair:
that he heard Ibn 'Abbas saying, "Thursday! And you know not what Thursday is?" After that Ibn 'Abbas wept till the stones on the ground were soaked with his tears. On that I asked Ibn 'Abbas, "What is (about) Thursday?" He said, "When the condition (i.e. health) of Allah's Apostle deteriorated, he said, ‘Bring me a bone of scapula, so that I may write something for you after which you will never go astray.’ The people differed in their opinions although it was improper to differ in front of a prophet. They said, ‘What is wrong with him? Do you think he is delirious? Ask him (to understand).’ The Prophet replied, ‘Leave me as I am in a better state than what you are asking me to do.’ Then the Prophet ordered them to do three things saying, ‘Turn out all the pagans from the Arabian Peninsula, show respect to all foreign delegates by giving them gifts as I used to do.’" The sub-narrator added, "The third order was something beneficial which either Ibn 'Abbas did not mention or he mentioned but I forgot." (Sahih al-Bukhari, Volume 4, Book 53, Number 393)
Narrated Ibn 'Abbas:
When Allah's Apostle was on his death-bed and in the house there were some people among whom was 'Umar bin Al-Khattab, the Prophet said, "Come, let me write for you a statement after which you will not go astray." 'Umar said, "The Prophet is seriously ill and you have the Qur'an; so the Book of Allah is enough for us." The people present in the house differed and quarrelled. Some said, "Go near so that the Prophet may write for you a statement after which you will not go astray," while the others said as Umar said. When they caused a hue and cry before the Prophet, Allah's Apostle said, "Go away!" Narrated 'Ubaidullah: Ibn 'Abbas used to say, "It was very unfortunate that Allah's Apostle was prevented from writing that statement for them because of their disagreement and noise." (Sahih al-Bukhari, Volume 7, Book 70, Number 573)
A side note: How interesting to find Umar and a group of unnamed companions of Muhammad stating that Allah’s book, i.e. the Quran, is all that is needed when we have Sunnis telling us all the time that Muslims also need Muhammad’s sunna since the Quran is insufficient.
Ahmad b. Hammad al-Dulabi – Sufyan – Sulayman b. Abi Muslim – Sa‘id b. Jubayr – Ibn ‘Abbas: Thursday, what a Thursday! He said: The Messenger of God’s pain because to severe that he said, "Give me [pen and paper] so that I may write a document for you and you will never go astray after me!" His companions wrangled over it, and it did not befit them to carry on a dispute before a prophet. Some people said, "What’s the matter with him! Is he talking nonsense? Ask him a question." [When] they went back, repeating [those remarks] to him, he replied, "Leave me [alone], the state that I am in is better than that for which you are calling me." He charged them with three things: … [Sa‘id b. Jubayr states that Ibn ‘Abbas] became silent about the third [command] either intentionally, or that he said that he had forgotten it.
Abu Kurayb and Salih b. Sammal – Waki’ – Malik b. Mighwal – Talhah b. Musarrif – Sa‘id b. Jubayr – Ibn ‘Abbas: Thursday, what a Thursday! [Sa‘id b. Jubayr:] Then I looked at Ibn ‘Abbas’ tears flowing on his cheeks as if they were a chain of pearls, [saying:] The Messenger of God said, "Bring me a tablet (lawh) and an inkpot (dawat), or a plank of the shoulder blade (katif) and an inkpot, so that I can write for you a document, after which you will not go astray." Some [people] said that the Messenger of God was talking deliriously. (The History of al-Tabari – The Last Years of the Prophet, translated and annotated by Ismail K. Poonawala [State University of New York (SUNY) Press, Albany 1990], Volume IX (9), pp. 174-175; bold and underline emphasis ours)
The translator adds some interesting notes:
1206. Baladhuri: They said: "Do you see him talking nonsense?" and [started] wrangling among themselves. The Messenger of God became grieved and annoyed and asked them to leave.
1207. The Prophet was not happy with ‘Umar because he did not cooperate with him when he asked for pen and paper. See Ibn Sa‘d, Tabaqat, II/2, 36-38; Buhl, Leben, 353: Momen, Shi‘i Islam, 15-16. The Shi‘is claim that the prophet wanted to make a written testament favoring ‘Ali’s succession as head of the nascent Islamic state but that ‘Umar foiled his plan. See Mirza, al-Balagh, I, 254-86. (Ibid., p. 174; bold and underline emphasis ours)
Thus, Allah humiliated his prophet by allowing him to come under the power of magic for a year which caused him to think that he was actually having sex with all of his wives. To see just how disgraceful this is one simply has to ask what was Muhammad actually doing during the entire year that he thought he was sleeping with his wives? Are we to assume that Muhammad was pleasuring himself in some manner which led him to think that he was actually engaging in intercourse?
Allah further disgraced Muhammad by permitting him to die in an excruciating manner, from the effects of poison, which led to a situation where his very own companions thought he was delirious, out of his mind, and speaking nonsense.
Allah did all this to him despite his promises in the Quran that he would protect his righteous servants from the Devil and insuring his messenger that Satan and the disbelievers would not be able to harm him by their schemes, which would obviously include such things as magic and poison (cf. Q. 5:67; 7:11-18; 15:32-44; 16:98-100 & 72:27-28).
