Abu Salamah bin Abd al-Rahman (may Allah have mercy on him) narrates from the Mother of the Believers, Sayyidah Aishah (may Allah be pleased with her), that she said: "During his illness the Messenger of Allah (peace and blessings be upon him) drew aside a curtain and opened a door, and he saw the people praying behind Sayyiduna Abu Bakr (may Allah be pleased with him). He (peace and blessings be upon him) was pleased at this sight and said: 'Al-hamdu lillah (All praise belongs to Allah); no prophet dies until a man from his ummah has led him in prayer.' Then he (peace and blessings be upon him) turned to the people and said: 'O people, whoever among you is struck by a calamity after me, let him find consolation for the calamity that befalls him by remembering the calamity of losing me; for no one of my ummah after me will ever be struck by a calamity like the calamity of losing me.'"
No one narrated this hadith from Abu Salamah bin Abd al-Rahman (may Allah have mercy on him) except Mus'ab bin Muhammad bin Shurahbil (may Allah have mercy on him), and Abdullah bin Ja'far (may Allah have mercy on him) is alone in narrating it.
