Narrated by Abu Barzah Nadlah ibn Ubayd al-Aslami (may Allah be pleased with him)

The Prophet (may peace & blessings of Allah be upon him) said:

A servant of Allah will remain standing on the Day of Judgment till he is questioned about his age and how he spent it;
and about his knowledge and how he utilized it;
about his wealth from where he acquired it
and in what (activities) he spent it;
and about his body as to how he used it.

Tirmidhi.
