Ibn Mas'ud (may Allah be pleased with him) narrates from the Prophet (peace and blessings be upon him), he said: "On the Day of Resurrection, the feet of a person will not move (from the court of Allah) until he is questioned about five things: about his life—how he spent it; about his youth—where he wasted it; about his wealth—how he earned it and where he spent it; and about how much he acted upon the knowledge he had." Tirmidhi, and he said: This hadith is gharib. Its chain is weak. Narrated by al-Tirmidhi.
