'...the rational man, as long as he is of sound reason, must put aside several hours during the day an hour for conversing with his Lord, an hour for [self-scrutiny and] accounting for himself, an hour to ponder over Allah's favours bestowed upon him, and an hour to spend on his own lawful pleasures, for this one hour will be an aid to him in fulfilling his other hours, as well as a time to recuperate and relax.'
