It is narrated from Sayyiduna Samurah bin Jundub (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) led the Fajr prayer, then said: "Is anyone from such-and-such tribe present here? Your companion is being held back at the gate of Paradise because of a debt he owes."
