The 5 Heart Corrupters: #4 & #5 October 19, 2007Posted by shadows15 in Personality Development.
The Fourth Corrupter: Food
The corrupter of the heart is of two types:
One of them is that which corrupts it by itself like the forbidden which are two types:
- Forbidden relative to Allah like carcasses, blood, pork, wild animals that kill with the canine tooth and birds that kill with claws.
- Forbidden relative to Allah’s slaves, like stolen, maghsoob, kidnapped, and what is taken without the permission of the owner either by force or by shame and blame.
The second is what corrupts as a result of its quantity and its exceeding limits, like wasting permissible things, excessive filling of the stomach, for it makes acts of obedience burdensome and it preoccupies the heart with muzaawalat mu’nat al-batnah chasing after belly desires and trying for it until it captures it. If it captures zafara it he becomes preoccupied with muzaawalat following its tasarruf activities and protecting the self from its harm, and being hurt by its weight, and it strengthens the elements of desire. It paves paths for Satan and expands them, for he moves among humans in the veins. Fasting narrows its passages and closes his paths and filling the stomach paves paths and widens them. Whoever eats a lot, drinks a lot, sleeps a lot and loses a lot. In the famous hadeeth:
“No human fills a container worse than his stomach. Two small portions of food to straighten his backbone are sufficient. If he must [eat more], then let it be a third for food, a third for drink and a third for breathing.” 
The Fifth Corrupter: Excessive Sleep
It deadens the heart, makes the body heavy, wastes time, and gives birth to a lot of negligence and laziness. Some [types] of sleep are extremely disliked, and some are harmful to the body. The best form of sleep is what takes place when there exists a strong need for it. Sleep at the beginning of the night is more praiseworthy and beneficial than at the end of the night, and sleep in the middle of the day is better than at its beginning and end tarafayhi. The closer sleep is to the beginning and ending of the day the less the benefit and the more the harm. [This is] especially the case for sleeping in the after noon (‘asr) and sleeping at the beginning of the day, except for one who stayed awake all night.
And among the disliked aspects, according to the scholars, is sleep between Salaatul-Fajr and sunrise, for it is a time of special reward. For that time escape, among the saalikeen (travellers), is a great loss maziyyah. Even if they traveled all night they would not allow sitting down from the journey sayr at that time until sunrise, because it is the beginning of the day and its key. [It is] the time for provisions to be sent down [and distributed], the time for obtaining portions and the descent of blessings, and from it the day is established. The ruling regarding the whole day is [based on] the ruling regarding that portion. One should only sleep at that time if one is forced.
In general, the most balanced/moderate (a‘dal) and beneficial form of sleep, is sleep during the first portion of the night and the last sixth of the night. According to medical practitioners, the length of the most balanced form of sleep should be eight hours. In their view, more [sleep] than that or less than that will cause deviation in one’s natural disposition according to it bihasabihi.
Among the forms of sleep that are not beneficial also, is sleep in the first part of the night shortly after sunset until fahmatul-‘ishaa the darkness of ‘Ishaa goes. The Messenger of Allaah (r) used to dislike it. So it is disliked according to the Sharee‘ah and naturally.
As excessive sleep causes these defects aafaat, putting aside sleep and abandoning it causes other major defects like bad temperament, yabsihi dry personality and a warped disposition, as well as drying up of the humors  which aid in understanding and work, and it leads to illnesses mutlifah which will prevent one afflicted from benefiting either with his heart or body.
Existence [of the world] was established on the basis of justice (‘adl), so whoever adheres to moderation has grabbed his portion of the confluence of good.
