“Your time should not be without any structure, such that you occupy yourself arbitrarily with whatever comes along.
Rather, you must take account of yourself and order your worship during the day and the night, assigning to each period of time an activity that must not be neglected nor replaced by another activity.
By this ordering of time, the blessing in time will show itself. A person who leaves himself without a plan as animals do, not knowing what he is to do at any given moment, will spend most of his time fruitlessly.
Your time is your life, and your life is your capital: by it you make your trade, and by it you will reach the eternal bounties in the proximity of Allah.
Every single breath of yours is a priceless jewel, because it is irreplaceable; once it is gone, there is no return for it.
So do not be like fools who rejoice each day as their wealth increases while their lives decrease. What good is there in wealth that increases while one’s lifespan decreases?
Do not rejoice except in an increase of knowledge or an increase of good works.
Truly they are your two friends who will accompany you in your grave, when your spouse, your wealth, your children, and your friends will remain behind.”
— Imam al-Ghazali
