Hadith

In the Name of Allah, the Most Gracious, the Most Merciful.

Abu Barza Nadla ibn 'Ubayd al-Aslami reported that the Messenger of Allah, may Allah bless him and grant him peace, said, "A slave will remain standing until he is asked about his life and how he spent it, his knowledge and how he acted regarding it, his property and how he acquired it and spent it, and his body and how he wore it out."
