You objected to his father — now you object to him.
You objected to his father — now you object to him. By God Osama is capable of holding this position, as his father was." The Prophet then came down from the pulpit, and the Muslims who were going to the camp site at Jorf said good-bye. The Prophet's health deteriorated, and Osama visited him when the Prophet was unable to speak — he could only kiss Osama good-bye.
The next Monday the Prophet was better, and he received Osama saying, "Go, good luck to you." Osama returned to the camp and ordered the march. Just as he was going to mount his horse, a message came from his mother saying that the Prophet was critically ill. Osama, ‘Omar and Abu ‘Obaydah returned to Medina, and that same day the Prophet passed away.
After the death of the Prophet, when Abu Bakr became Caliph, he ordered Osama to undertake the same mission as ordered by the Prophet, (Ibn ‘Asaker vol.l, p.433). On page 438 Ibn ‘Asaker also says, “Abu Bakr told Osama that the Prophet had given all necessary instructions, and he was not adding anything to them. Abu Bakr did not listen to those who advised him that expedition be postponed.” Comparison Comparison between the above two ways of recording.
There are some points worth mentioning about Saif's recording. He says: The army was crossing the moat of Medina when the Prophet died. Saif included this sentence in his book to conceal the fact that there were delays which prevented the army from setting out; and there were no disruptions by the trouble makers who caused the delays.
Yet in his more lucid moments Muhammad was annoyed that the army was delayed, and repeated his original order, "Osama's army must march." Saif says, "When Osama heard that the Prophet had passed away he sent ‘Omar to the successor of the Prophet of God to obtain his permission for the return of the army to Medina." Other instructions say, "Osama heard that the Prophet's condition was serious, so he went to Medina with ‘Omar, Abu Bakr and Abu ‘Obaydah.
(Some say that Abu ‘Obaydah was not with them.) After the death of the Prophet, and after Abu Bakr's nomination at Saqifa, and his final election at the Mosque, he dealt with Osama's army. Here again Saif back dates the successorship of Abu Bakr, making it appear that he was appointed Caliph (successor) before the death of the Prophet. Saif says, "Ansar (helpers) asked Abu Bakr to dismiss Osama and appoint another commander to the army.
