It is narrated from Hazrat Samurah (may Allah be pleased with him) that once the Prophet (peace and blessings be upon him) led the Fajr prayer, and after the prayer he said, "Is there anyone here from such-and-such tribe?" A man said, "Yes! (We are present)." The Prophet (peace and blessings be upon him) said, "Your companion (who has passed away) has been held back at the gate of Paradise because of a debt he owed, so you should pay off his debt."
