Musannaf Ibn Abi Shaybah

It is narrated from Hazrat Mu'adh that he says: On the Day of Judgment, a servant's feet will not move from their place until he is questioned about four things: about his body—how he wore it out; about his life—how he spent it; about his wealth—from where he earned it and where he spent it; and about his knowledge—how much he acted upon it.
