The 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-JawziyyaThe perfection of Tawheed is found when there remains nothing in the heart except Allaah
Ibn Qayyim Al-JawziyyaSpeech remains as a slave to you, but the moment it leaves your mouth, you become its slave.
Ibn Qayyim Al-JawziyyaSatan rejoiced when Adam (peace be upon him) came out of Paradise, but he did not know that when a diver sinks into the sea, he collects pearls and then rises again.
Ibn Qayyim Al-JawziyyaA slave stands infront of Allah on two occasions. The first during salah, and secondly on the Day of Judgment. Whoseover stands correctly in the first, the second standing will be made easier for him. And whosoever, disregards the first standing, the second standing will be extremely difficult.
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.
