The most important thing which can be stated in regards to the preson in such a stae is that he does not have any religious excuse which he can use such that he could, for example, say that “I was in a state of anger and thus I did so and so…” We also see that, perhaps a majority of people murdered, are killed when the killer was in a fit of anger and rage since no one would take a knife and slit someone's throat when he is cool and collected!
Anger is one of the most dangerous tools as Satan is able to use it to make people commit sins Anger is one of the gifts from Allah (SwT) which can also be used in incorrect and inappropriate places. As we know, the power of anger actually refers to the gathering of a person's physical energy in the face of a difficulty.
Therefore, Allah (SwT) is the one who has created the power of anger so that a person would be able to defend himself from an attack, as if a person was to remain indifferent in such situations and did not gather his inner-energy, then he would not be able to defend himself. There are some people who have stated that when a person is in his regular state, he has approximately 1/10th of his power ready to use.
However, when he gets into a state of anger, then his power becomes ten fold - meaning that all of their energy is mustered! With this point in mind, we see that in a regular state, some people are very relaxed, however when they enter into a stage of anger, then even five people would not be able to take charge over them and control them as all of their inner energy and power has been gathered together!
Therefore, the power of anger which Allah (SwT) has created within everyone is actually one of His blessings, however it must be used in the proper way. With this said, we understand that anger is of two types: the unbefitting form of anger and the praiseworthy and obligatory anger.
In the face of those who openly perform sins and transgress the laws of Allah (SwT), the true believer must show his Islamic zeal and enthusiasm in opposing the impermissible acts and must not be indifferent to sins happening around him. There is a well-known tradition which states that once, Allah (SwT) sent a group of Angels to destroy a particular nation, however they did not fulfill the responsibility given to them by Allah (SwT) and returned back, appealing to Him, saying: “O' Allah!
Within this group (whom we are commanded to destroy) we saw a very old man who worships You in the darkness of the night.
