There are ten useless matters:
1. Knowledge that is not acted on
2. The deed that has neither sincerity nor is based on following the righteous examples of others
3. Money that is hoarded, as the owner neither enjoys it during this life nor obtains any reward for it in the Hereafter
4. The heart that is empty of love and longing for God, and of seeking closeness to Him
5. A body that does not obey and serve God
6. Loving Allah without following His orders or seeking His pleasure
7. Time that is not spent in expiating sins or seizing opportunities to do good
8. A mind that thinks about useless matters
9. Serving those who do not bring you close to God, nor benefit you in your life
10. Hoping and fearing whoever is under the authority of God in His hand; while he cannot bring any benefit or harm to himself, nor death, nor life; nor can he resurrect himself.
However the greater of these matters are wasting the heart and wasting time.
- Ibn al Qayyim al Jawziyya
