After performing the farewell Hajj, Rasulullah left for Madinah. He wanted to say farewell to those martyrs who had laid down their lives for the cause of Islaam. So he went to Uhad and made dua for those who had achieved martyrdom and everlasting life. After his visit to Uhad our beloved Nabi visited the cemetery of the Muslims called "Jannatul Baqi" in Madinah and made dua for their departed souls.
In the month of Muharram 11 A.H. he fell ill with fever which became worse from day to day. When the illness became worse then Rasulullah sought permission from his wives to spend his final days in the house of Hazrat Ayesha (R.A.) The last Salaat that he could lead in Jama'at was the Maghrib Salaat and when his health failed him he directed: "Let Abu Bakr (R.A.) lead the prayer". Rasulullah 's house was adjoining Masjid-e-Nabwi and from his house he saw the Muslims engaged in Salaat. This pleased the Rasool of Allah very much. The health of our Nabi got worse and on Monday, 12th Rabiul-Awwal 11A.H. the greatest leader of mankind passed away.
Hazrat Fadal bin Abbas (R.A.) Hazrat Ali (R.A.), Hazrat Usama (R.A.) gave the body a ghusal (bath) and it was lowered into the grave in the very apartment of his wife Hazrat Bibi Ayesha (R.A.) where he breathed his last.
