Each breath of yours is a priceless jewel, since each of them is irreplaceable, & once gone can never be retrieved.
 
Don't be like the deceived fools who are joyous because each day their wealth increases while their life shortens.

What good is an increase in wealth when life grows shorter?

Therefore be joyous only for an increase in knowledge or in good work, for they are your two companions who will accompany you in your grave when your wealth, family & friends stay behind.

 
Imam Al-Ghazali
