'' 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 سبحانه وتعالى. 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 the fools who rejoice each day as their wealth increases while their lives decrease. What good is there in wealth that increases while one's life-span 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.''

(The Beginning of Guidance: Imam Al-Ghazali)
