The health of the Prophet grew worse. His last days were remarkable for the calmness and serenity of his mind. He was able, though weak and feeble, to lead the public prayers until within three days of his death. He requested that he might be permitted to stay at Aisha's house close to the mosque during his illness, an arrangement to which his other wives assented. As long as his strength lasted, he took part in the public prayers. The last time he appeared in the mosque he addressed the congregation, after the usual prayers were over, in the following words: "0 Muslims, if I have wronged anyone of you, here I am to answer for it; if I owe anything to anyone, all I may happen to possess belongs to you." A man in the crowd rose and claimed three dirhams which he had given to a poor man at the request of the Prophet. They were immediately paid back with these words: "Better to blush in this world than in the next."

The Prophet then prayed and implored Allah's mercy for those who had fallen in the persecution of their enemies. He recommended to all his followers the observance of religious duties and the leading of a life of peace and goodwill. Then he spoke with emotion and with a voice still so powerful as to reach beyond the outer doors of the mosque: "By the Lord in Whose hand lies the soul of Muhammad as to myself, no man can lay hold on me in any matter; I have not made lawful anything excepting what Allah has made lawful; nor have I prohibited anything but that which Allah in His Book has prohibited."

Then turning to the women who sat close by, he exclaimed: "0 Fatimah, my daughter, and Safia, my aunt, work you both that which will procure your acceptance with the Lord, for verily I have no power to save you in any wise." He then rose and re-entered the house of Aisha.
