Al-Munafiqun (The Hypocrites)
Chapter 63: Verse 4
Inside a certain class of people there rages an internal war, one that doesn't take place on the battlefield, but in one's bedroom, one's office, one's own home. It is a war that results in ulcers or an increase in blood pressure. Everything frustrates these people: they become angry at inflation, furious because the rains came late and exasperated when the value of their currency falls. They are forever worried and irritated, no matter what the reason.
We should not carry the weight of the globe on our shoulders. Let the ground carry the burden of those things that happen. Some people have a heart that is like a sponge, absorbing all kinds of fallacies and misconceptions. It is troubled by the most insignificant of matters; it is the kind of heart that is sure to destroy its possessor.
Those who are principled and are upon the true path are not shaken by hardship; instead, hardship helps to strengthen their resolve and faith. But the reverse is true for the weak-hearted: when they face adversity or trouble, it is only their level of fear that increases. At a time of calamity, there is nothing more beneficial than having a brave heart. The one who has such a heart is self-possessed; he has firm faith and cool nerves. On the other hand, during the course of any given day, the coward slaughters himself many times with apprehensions and presentiments of impending doom. Therefore, if you desire for yourself a stable life, face all situations with bravery and perseverance.
