Based on lesson of Ibn Qayyim al-Jawziyyah :-
1) --Our Knowledge-- Wasted by not taking action with it.
2. --Our Actions-- Wasted by committing them without sincerity.
3.
--Our Wealth-- Wasted by using on things that will not bring us ajr. We
waste our money, our status, our authority, on things which have no
benefit in this life or in hereafter.
4. --Our Hearts-- Wasted
because they are empty from the love of Allah, and the feeling of
longing to go to Him, and a feeling of peace and contentment. In its
place, our hearts are filled with something or someone else.
5. --Our Bodies-- Wasted because we don't use them in worship and service of Allah
6. --Our Love-- Our emotional love is misdirected, not towards Allah, but towards something/someone else.
7.
--Our Time-- Wasted, not used properly, to compensate for that which
has passed, by doing what is righteous to make up for past deeds
8.
--Our Intellect-- Wasted on things that are not beneficial, that are
detrimental to society and the individual, not in contemplation or
reflection.
9. --Our Service-- Wasted in service of someone who will not bring us closer to Allah, or benefit in this world
10. --Our Zikr-- Wasted, because it does not affect us or our hearts.
Let us muhasabah friends...^_^ May He forgives us... :)
