Losing time is harder than death, as losing time keeps you away from Allah and the Hereafter, while death keeps you away from the worldly life and people.
Ibn Qayyim Al-JawziyyaThe soul will never become pious and purified except through undergoing afflictions. It is the same as gold that can never be pure except after removing all the base metals in it.
Ibn Qayyim Al-JawziyyaThis wordly life is like a shadow. If you try to catch it, you will never be able to do so. If you turn your back towards it, it has no choice but to follow you.
Ibn Qayyim Al-JawziyyaRepel the thought, for if you don't, it becomes an idea. So repel the idea, for if you don't it will become a desire. So fight against that(desire), for if you don't, it will become a determination and a passion. And if you don't repel that, it will become an action. And if you don't replace it with its opposite, it will become a constant habit. So at that point, it will be difficult for you to change it.
