Why do you not understand that your basic duty is not to labor like an animal, but to expend effort for a true, perpetual life, like a true human being.
Besides, the worldly works are trivial matters that mostly
do not concern you, and that you meddle in officiously and confuse. You leave
aside the essential things and pass your time in acquiring inessential
information as if you were going to live for thousands of years.
As a result: O man! Know that yesterday has left you, and as
for tomorrow, you have nothing to prove that it will be yours. In which case,
know that your true life is the present day. So throw at least one of its hours
into a mosque or prayer-mat, a coffer for the hereafter like a reserve fund,
set up for the true future.
