When Allah granted Prophet Yoosuf (`alayhis-Salaam) physical beauty it caused him to be locked up in the prison; but when Allah granted him knowledge (when he interpreted the dream of the king) it not only took him out of prison, but elevated his rank in society, clearly showing us the virtue of knowledge and that physical beauty does not mean anything.
Ibn Qayyim Al-JawziyyaSins have many side-effects. One of them is that they steal knowledge from you.
Ibn Qayyim Al-JawziyyaThe perfection of Tawheed is found when there remains nothing in the heart except Allaah
Ibn Qayyim Al-JawziyyaEvery gulp of air that goes out in a cause other than the cause of Allah will turn to sorrow and regret on the Day of Judgement.
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-JawziyyaTruly in the heart there is a void that can not be removed except with the company of Allah. And in it there is a sadness that can not be removed except with the happiness of knowing Allah and being true to Him. And in it there is an emptiness that can not be filled except with love for Him and by turning to Him and always remembering Him. And if a person were given all of the world and what is in it, it would not fill this emptiness.
Ibn Qayyim Al-Jawziyya
