I would like to tell you that during my student life I suffered from vanity. Whenever I read a book, memorized some text, or prepared for a lesson, I would be affected by the disease of vanity. This, as you well know, is something which prevents me from gaining Islamic knowledge. My question is, firstly, what are the books which discuss the biography of the righteous predecessors and their absolute devotion to learning and worshipping Allaah? Reading these books, as you well know, helps to cure the disease of vanity from which people suffer. Secondly, is there anything else you can advise me to help rid me of this disease?
