It is narrated from Sayyiduna Ubaid bin Khalid that the Prophet (peace and blessings be upon him) established brotherhood between two men. One of them was martyred during the time of the Prophet (peace and blessings be upon him), and after some time, the other died a natural death. People began to pray for him. The Prophet (peace and blessings be upon him) said: What are you praying for? We replied: We are saying, O Allah, forgive him, have mercy on him, and grant him the companionship of his friend. The Prophet (peace and blessings be upon him) said: Then where are the prayers he offered after the martyr? Where are the fasts he kept later, or the deeds he performed? The distance between the two is greater than that between the earth and the sky.
