Simple life is life that is not excessive. Does not show luxury in crowded. Simple is to be proportional.
Man is endowed with the God of reason and lust, Ideally reason can lead the passions of human desire to survive in his life, but human passions sometimes like water, flowing as long as there is still an open gap, The difference when water flows to the lower place, while the lust to direction otherwise ..
The human nature enslaved by its lusts has always never been satisfied, And will be the ones who lost its sensitivity. Can not be grateful for what Allah has given. Can not realize what is going on around her.
Of course it is very important, because in Islam very uphold the ropes of brotherhood.
For the good of Islam the concept of simple lifestyle is done by his people. Then what is called a simple?
Simple is not synonymous with all-round deprivation or poverty, because simple is the sense of self-sufficiency with what is received.
Simple life is life is not excessive. Not showing luxury in crowded. Simple is to be proportional. Put something in place.
In other words, Islam encourages its people to be rich and so on qonaah. To self sufficiently, to help the interests as much as possible. This is called the wealth of the soul, the riches of blessing.
Examples that embrace such a life have been exemplified by friends and sahabiyah. How they live modestly in their daily life, when they give charity is not half-hearted. How very simple is the life of the Messenger of Allah, no one is ever absent to sacrifice with the best cattle.
Living a proportional life though more than adequate, to hear and help the orphans sincerely is a mirror of true believers. He feels comfortable with the simplicity that decorates him. Because he realized it was simple it was very beautiful.
Wasalam ..
