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-JawziyyaWhen there is money in your hand and not in your heart, it will not harm you even if it is a lot; and when it is in your heart, it will harm you even if there is none in your hands.
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-JawziyyaWhoever mocks his brother for a sin they repented from will not die till he himself falls into the same sin.
