Yearning for Allah and His meeting is like the gentle breeze blowing upon the heart, extinguishing the blaze of the Dunya. Whosoever caused his heart to settle with his Lord shall be in a state, calm and tranquility, and whosoever sent it amongst the people shall be disturbed and excessively perturbed.
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-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.
Ibn Qayyim Al-JawziyyaThe sinner does not feel any remorse over his sins, that is because his heart is already dead
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-Jawziyya
