Doom comes about because of neglecting to evaluate one's self and because of just following one's whims.
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-JawziyyaAs you can taste a pot full of food with a spoon likewise someone's tounge can tell you about his heart.
Ibn Qayyim Al-JawziyyaThe hijrah to Allah includes abandoning what He hates and doing what He loves and accepts.
Ibn Qayyim Al-JawziyyaHow strange! You lose a little from you and you cry. And your whole life is wasting and you're laughing
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.
