Doom comes about because of neglecting to evaluate one's self and because of just following one's whims.
Ibn Qayyim Al-JawziyyaThe sinner does not feel any remorse over his sins, that is because his heart is already dead
Ibn Qayyim Al-JawziyyaPatience is that the heart does not feel anger towards that which is destined and that the mouth does not complain.
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-Jawziyya
