This booklet is a message from Al-Imam Al-Ghazali to one of his disciples who asked the Imam to advise him concerning the sciences which would benefit him in the Hereafter so he would adhere to them; as well as that which would not benefit him so that he would abandon them. In response the Imam wrote this epistle to show his disciple the good and the evil deeds; the deeds which draw one near to Allah the Almighty and the importance of working for the Hereafter. He also explains that one should not forbid an act, then perform it. The booklet contains other useful advice.
