Four Matters - Body, Lifetime, Wealth and Knowledge

Mu’adh ibn Jabal reported: The Messenger of Allah, peace and blessings be upon him, said, 

“The feet of a servant will not move on the Day of Resurrection until he is asked about four matters: his body and how he used it, his lifetime and how he exhausted it, his wealth and how he acquired it and spent it, and his knowledge and how he acted upon it.”
