Whoever desires to purify his heart, then let him prefer Allah to his desires
Ibn Qayyim Al-JawziyyaIf you knew the true value of yourself, you will never allow yourself to be humiliated by committing sins.
Ibn Qayyim Al-JawziyyaThe sea of pleasures may drown its owner and the swimmer fears to open his eyes under the water.
Ibn Qayyim Al-JawziyyaO you, who spends his lifetime disobeying his Lord, no one amongst your enemies is wicked to you more than you are to yourself
Ibn Qayyim Al-JawziyyaThe keys to the life of the heart lie in reflecting upon the Quran, being humble before Allah in secret, and leaving sins.
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.
