There 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.
Ibn Qayyim Al-JawziyyaThe ibtilaa' (testing) of the believer is like medicine for him. It cures him from illness. Had the illness remained it would destroy him or diminish his reward and level (in the hereafter). The tests and the trials extract these illnesses from him and prepare him for the perfect reward and the highest of degrees (in the life to come).
Ibn Qayyim Al-JawziyyaHow strange! You lose a little from you and you cry. And your whole life is wasting and you're laughing
Ibn Qayyim Al-JawziyyaAs you can taste a pot full of food with a spoon likewise someone's tounge can tell you about his heart.
Ibn Qayyim Al-JawziyyaAnd to have spent the night sleeping and awoken regretful, is better than to have spent the night standing (in prayer) and awaken impressed with oneself!
