Sayyiduna Jabir bin Abdullah (may Allah be pleased with them both) narrates: The Prophet Muhammad (peace and blessings be upon him) came to the grave of Abdullah bin Ubayy after he had been placed in his grave. By the order of the Prophet (peace and blessings be upon him), he was taken out. The Prophet (peace and blessings be upon him) placed him on his knee, put his blessed saliva on him, and clothed him with his own shirt. Allah knows best about the rest.
