Al-GhazaliNeglect not your time, nor use it haphazardly; on the contrary you should bring yourself to account. Structure your litanies and other practices during each day and night. This is how to bring about the spiritual blessing (baraka) in each period. If each of your breaths is a priceless jewel, Be not like the deceived fools who are joyous because each day their wealth increases while their life grows ever shorter.

Al-GhazaliThere are two kinds of Riya - Showing off-Ostentation ie pure ostentation and adulterated ostention. In pure ostentation "Riya" a man does a good deed only for worldly benefit. In Adulterated ostentation, a man does a good deed with the intention of reaping the benefits of the world as well as of the Hereafter.
