Four Poisons of the Heart
1. Unnecessary Talking
Umar Ibn al-Khattab, may Allah be pleased with him, said: "A
person who talks too much is a person who often makes mistakes,
and someone who often makes mistakes, often has wrong actions.
The Fire has a priority over such a frequent sinner."
2. Unrestrained Glances
It has been related that the Prophet (saw) once said words to
the effect: "The glance is a poisoned arrow of shaytan. Whoever
lowers his gaze for Allah, He will bestow upon him a refreshing
sweetness which he will find in his heart on the day that he
meets Him."
3. Too Much Food
Al-Miqdam ibn Ma'd Yakrib said: "I heard the Messenger of Allah
(saw) say: "The son of Adam fills no vessel more displeasing to
Allah than his stomach. A few morsels should be enough for him
to preserve his strength. If he must fill it, then he should
allow a third for his food, a third for his drink and leave a
third empty for easy breathing."
4. Keeping Bad Company
Allah's Apostle said, "The example of a good companion (who
sits with you) in comparison with a bad one, is like that of
the musk seller and the blacksmith's bellows (or furnace); from
the first you would either buy musk or enjoy its good smell
while the bellows would either burn your clothes or your house,
or you get a bad nasty smell thereof." From the Muslim
perspective, the purpose of education is to produce a human
being who is safe to himself and to his society. The end result
is a human being who knows his place in the universe and knows
his purpose. He knows his rights and his responsibilities, with
the emphasis on responsibility.
