1. Our Knowledge
Wasted by not taking action with it.
2. Our Actions
Wasted by committing them without sincerity.

Wasted by using on things that will not bring us ajr (reward from Allah). We waste our money, our status, our authority, on things which have no benefit in this life or in the akhirah (hereafter).
4. Our Hearts

9. Our Service
Wasted in service of someone who will not bring us closer to Allah, moreover something that will benefit us in dunya.
10. Our Dhikr (Remembrence of Allah)
Wasted, because it does not effect us or our hearts.
