"Beware, in the body there is a flesh; if it is sound, the whole body is sound, and if it is corrupt, the whole body is corrupt, and behold, it is the heart." {Bukhari & Muslim} The heart (the core of our personality) is the storage place for knowledge and wisdom, and it can guide us along the path towards Allah’s pleasure. The heart, however, can be afflicted by diseases like anger, envy, ostentation, arrogance, stinginess and love of position & power. Diseases that preoccupy the heart, divert it away from the love of Allah. Each and every one needs to inspect his heart carefully to diagnose any affliction, and search for cures. Purification of the heart or Tazkiya e Nafs is a series of lectures that will help you identify the disease and take steps to cure it, inshaAllah.
