and Allah said "And proclaim the pilgramage among men; they will come to thee on foot and on every kind of camel. Lean on account of Journeys through deep and distant mountain highways" Surah 22 ~ Al Hajj Part 27
The other two pretenders, Tulayha and Harun by name, were not suppressed until after the death of the Prophet, during the reign of Abu Bakr. Harun, better known as Mussaylamah, addressed to the Prophet a letter which ran as follows: "From Mussaylamah the Prophet of Allah, to Muhammad the Prophet of Allah. Peace be to you. I am your partner. Let the exercise of authority be divided between us. Half the earth will be mine, and half will belong to your Quraish. But the Quraish are too greedy to be satisfied with a just division." To this letter the Prophet replied as follows: "From Muhammad the Messenger of Allah to Mussaylamah the liar. Peace be to those who follow the right path. The earth belongs to Allah. It is He Who makes the reign whomsoever He pleases. Only those will prosper who fear the Lord."
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:
"O 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 Dhirhams 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: "O Fatima, my, daughter, and Safia, my aunt, work you both that which procure you 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.
After this, the Prophet never appeared at public prayers. A few hours after he returned from the mosque, the Prophet died while laying his head on the bosom of Aisha. As soon as the Prophet's death was announced, a crowd of people gathered at the door of the house of Aisha, exclaiming: "How can our messenger be dead?" Umar said: "No, he is not dead; he will be restored to us, and those are traitors to the cause of Islam who say he is dead. If they say so let them be cut in pieces." But Abu Bakr entered the house at this moment, and after he had touched the body of the Prophet with a demonstration of profound affection, he appear at the door and addressed the crowd with the following speech: "O Muslims, if anyone of you has been worshipping Muhammad, then let me tell you that Muhammad is dead. But if you really do worship Allah then know that Allah is living and will never die. Do you forget the verse in the Quran:
Muhammad is not more than a Messenger and indeed (many) Messengers have passed away before him. If he dies or is killed, will you then turn your back on your heels (as disbelivers)? And he who turns back on his heels, not the least harm will he do to Allah, and Allah will give reward to those who are grateful." ( 3:144 Quran).
Upon hearing this speech of Abu Bakr, 'Umar acknowledged his error, and the crowd was satisfied and dispersed.
Al-Abbas, the Prophet's uncle, presided at the preparation for the burial, and the body was duly washed and perfumed. There was some dispute between the Quraish and the Ansar as to the place of burial; however, Abu Bakr settled the dispute by affirming that he had heard the Prophet say that a prophet should be buried at the very spot where he died. A grave was accordingly dug in the ground within the house of Aisha and under the bed on which the Prophet died. In this grave the body was buried, and the usual rites were performed by those who were present.
Thus ended the glorious life of Prophet Muhammad.
May the peace and blessings of Allah be upon him.
