However...
However, one who does not give importance to the world is guaranteed to have a body and soul which are at rest and tranquil. These Divine commandments are not simply points that have importance in the next life, rather, their rewards and punishments will be physically manifested while in this world as well.
Even if, may Allah (SwT) protect us from such thoughts, there was no after-life, then it still would have been necessary to think about the implementation of these commandments for the life of this world and for the ease and comfort of our body and soul. It is said that with the advancements in medicine, the number of physical sicknesses has been reduced. However the number of spiritual and psychological ailments are increasing day by day.
Perhaps we will reach a day when the world, in our words, will reach to becoming a great big place of “دار المجانين” or the “Abode of the Insane Ones” and across the entire Earth, we may not be able to find one person at ease and free from any spiritual sicknesses! The mental and psychological illnesses are increasing day by day and are all related to external factors. A person who has a strong affinity to the material world will see his soul being continuously tortured.
Truthfully this verse of the Qur`an is the prescription for the health of our soul, and the asceticism which has been mentioned in these two lines of the tradition under review have actually been summarized in the verse of the Qur`an mentioned above. The material life of the people of true faith is very good since they do not gain tranquility through wealth, nor do they consider status in the society as that which brings them happiness.
As can be seen, there are people who have all of the material possessions of this life, however they are the worst off! They are constantly in anxiety and stress, and hope that no one takes what they have, nor tries to pull the wool over their eyes! Thus, these types of people are continuously in mental punishment and torture.
