Repel 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 heart becomes sick, as the body becomes sick, and its remedy is al-Tawbah (repentance) and protection [from transgression]. It becomes rusty as a mirror becomes rusty, and its clarity is obtained by remembrance. It becomes naked as the body becomes naked, and its beautification is al-Taqwa. It becomes hungry and thirsty as the body becomes hungry, and its food and drink are knowledge, love, dependence, repentance and servitude.
Ibn Qayyim Al-JawziyyaAs long as one is following the right way, one should never be concerned about the reproaches of those who like to find faults.
Ibn Qayyim Al-JawziyyaThere are six stages to knowledge: Firstly: Asking questions in a good manner. Secondly: Remaining quiet and listening attentively. Thirdly: Understanding well. Fourthly: Memorising. Fifthly: Teaching. Sixthly- and it is its fruit: Acting upon the knowledge and keeping to its limits.
