What did the Prophet Muhammad (saw) do when a dead man was brought to him and they asked him to lead the funeral prayer?
      Narrated Salama bin Al-Akwa:                          Once, while we were sitting in the company of Prophet, a dead man was      brought. The Prophet was requested to lead the funeral prayer for the      deceased. He said, "Is he in debt?" The people replied in the      negative. He said, "Has he left any wealth?" They said, "No." So, he      led his funeral prayer. Another dead man was brought and the people      said, "O Allah's Apostle! Lead his funeral prayer." The Prophet said,      "Is he in debt?" They said, "Yes." He said, "Has he left any wealth?"      They said, ''Three Dinars." So, he led the prayer. Then a third dead      man was brought and the people said (to the Prophet ), Please lead his     funeral prayer." He said, "Has he left any wealth?" They said, "No."      He asked, "Is he in debt?" They said, ("Yes! He has to pay) three      Diners.', He (refused to pray and) said, "Then pray for your (dead)      companion." Abu Qatada said, "O Allah's Apostle! Lead his funeral      prayer, and I will pay his debt." So, he led the prayer.
