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-JawziyyaThis wordly life is like a shadow. If you try to catch it, you will never be able to do so. If you turn your back towards it, it has no choice but to follow you.
Ibn Qayyim Al-JawziyyaAnd verily for everything that a slave loses there is a substitute, but the one who loses Allah will never find anything to replace Him.
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-JawziyyaFrom the perfection of Allah's ihsan is that He allows His slave to taste the bitterness of the break before the sweetness of the mend. So He does not break his believing slave, except to mend him. And He does not withhold from him, except to give him. And He does not test him (with hardship), except to cure him.
