As a Muslim, you should strive the utmost best to maximise your time, as life is short...next day you never know it will be you who is gone! so the Muslim should take advantage of every minute he has in his life. Do that which brings you closer to Allah, one of the affective ways in maximising your time is to have a set schedule so you may know what you are doing thus being able to take advantage of time!!
