On the 19th of Safar of 11 A.
On the 19th of Safar of 11 A.H., it was his turn to sleep in the chamber of Ayesha. At night, he paid a visit to the cemetery of Al-Baqi in the company of his servant, Abu Muwayhibah, who later reported that: “The Apostle stood between the graves and addressed them in the following words: 'Peace be upon you who are in these graves. Blessed are you in your present state to which you have emerged from the state in which the people live on earth.
Subversive attacks are falling one after another like waves of darkness, each worse than the previous ones.'“ Muhammad Husayn Haykal says that the (fatal) sickness of the Prophet began on the morning following the night on which he had visited the cemetery, i.e., on 20th of Safar. He further says: It was then that the people became concerned and the army of Usamah did not move.
True, the report of Abu Muwayhibah is doubted by many historians who believe that Muhammad's sickness could not have been the only reason that prevented the army from marching to al-Sham, that another cause was the disappointment of many, including a number of senior Muhajireen and Ansar, in regard to the leadership of the army.
(The Life of Muhammad, Cairo, 1935) The following incident appears to have taken place on the morning of the 20th of Safar: Sir William Muir One night the Prophet walked to the burial ground in the outskirts of the city. There he waited long absorbed in meditation and praying for the dead. In the morning, passing by the door of Ayesha, who was suffering from a severe headache, he heard her moaning: my head! oh, my head!
He entered and said: “Nay, Ayesha, it is rather I that have need to cry my head, my head!” Then in a tender strain: “But wouldst thou not desire to be taken whilst I am yet alive; so that I might pray over thee, and wrapping thee, Ayesha, in thy winding sheet, thus commit thee to the grave?” “That happen to another,” exclaimed Ayesha, “and not to me!” archly adding: “Ah, that is what thou art desirous of!
Truly, I can fancy thee, after having done all this and buried me, return straightway to my house, and spend that very evening in sporting in my place with another wife!” The Prophet smiled at Ayesha's raillery, but his sickness pressed on him too heavily to admit of a rejoinder in the same strain.
