It is narrated from Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "On the Day of Resurrection the feet of the son of Adam will not move away from before his Lord until he is asked about five things: about his life, in what he spent it; about his youth, in what he wore it out; about his wealth, from where he earned it and on what he spent it; and what he did with what he knew."
