Causes:
 
"O, believers, within the man whose temper is irritable the fire of wrath speads sparks when he becomes heated by a fit of anger, owing to that irritability, and in that excitement, when it appears, are burnt (the fruits of) his faith, pious actions, his reward (for them), worship, purity of heart, decency, understanding, and intelligence. Then the fire of sensuousness flares up in him, causing him to feel the desire for tasty foods, causing him to make designs upon the property, position, rank and wives of others, making him wish to eat and dress well, under the influence of the fire of greed. This is Hell, it will reduce thee to nothingness, throwing thee headlong into the pit. Control as much as you can of the forces of irritability and sensuousness, so that they may not shake you in your position, will not throw you out of balance, stirring up, and causing change in yourself, in your original nature. This is because as soon as man has been brought out of the normal state, he becomes a brute without faith."
