Bukhari

Hadith Commentary:
Perhaps this person was prone to great anger. Therefore, this particular advice was given precedence over all others for him. Thus, giving advice according to the specific situation is the Sunnah of the Prophet (sallallahu alayhi wa sallam), just as it is obligatory upon every wise person to prescribe medicine according to the condition of the illness.

Hadith Commentary:
(1)
An experienced physician is one who diagnoses the illness and then prescribes the remedy. The Messenger of Allah (sallallahu alayhi wa sallam) diagnosed that this person is one who possesses great anger, and from this many spiritual ailments arise. Therefore, you (sallallahu alayhi wa sallam) said:
"Do not become angry."
(2)
Some scholars have interpreted this to mean: strive to avoid the causes of anger, and do not engage in those matters which lead to anger, because anger itself is a natural thing; it is not possible to eliminate it entirely.
In any case, the Messenger of Allah (sallallahu alayhi wa sallam), taking his condition into consideration, advised him to abandon anger and the causes of anger.
(Fath al-Bari: 10/639)

Explanation:
1:
No human being is free from the attribute of anger,
but gaining control over one’s anger is the greatest virtue and the most perfect trait of a person.
Advice should be given while considering the temperament and nature of the one being addressed, according to his circumstances.
Thus, in this hadith, the Prophet (sallallahu alayhi wa sallam), despite the man asking multiple times, gave him the same answer according to his situation, that is: Do not become angry.

Takhrij:
[بخاري 6116 ]

Benefits:
➊ Who was the questioner?
This question was asked to the Prophet sallallahu alayhi wa sallam by several Companions at different times, and he gave them the same answer. In Fath al-Bari, this question and the same answer from the Prophet sallallahu alayhi wa sallam are mentioned from Jariyah bin Qudamah, Sufyan bin Abdullah Thaqafi, Abu al-Darda, and Ibn Umar radi Allahu anhum. Some of them asked by saying, “Tell me something brief from which I may benefit,” and some said, “Tell me a deed that will admit me to Paradise.” The Prophet sallallahu alayhi wa sallam replied, “Do not get angry.” For details of all the narrations, see: [فتح الباري حديث 6116]

➋ The Prophet’s sallallahu alayhi wa sallam response to the seeker of advice
In reality, the Messenger of Allah sallallahu alayhi wa sallam, in response to such requests, has given other pieces of advice as well.
To some he said:
«قل ربي الله ثم استقم»
“Say: My Lord is Allah, then remain steadfast upon it.” [صحيح الترمذي - الزهد 47]
To others he said:
«لا يزال لسانك رطبا من ذكر الله»
“Let your tongue always be moist with the remembrance of Allah.” [ترمذي 458/5 اور صحيح ابن ماجه 317/2]
The scholars state that just as an expert physician prescribes treatment and diet for each patient according to his temperament and illness, similarly, the Messenger of Allah sallallahu alayhi wa sallam, who was the greatest spiritual healer, would advise each person with the deed that was necessary and suitable for his circumstances. It appears that among these individuals, anger was more prevalent, so the Prophet sallallahu alayhi wa sallam, despite repeated questioning, advised them to avoid anger. Since almost all people tend to lose moderation when angry, this advice of the Prophet sallallahu alayhi wa sallam is for all Muslims.

➌ The harms of anger
The Messenger of Allah sallallahu alayhi wa sallam, by commanding us to avoid anger, has arranged for us to be saved from countless evils, because the fire of anger causes a person’s face and eyes to become red, his hands and feet begin to tremble, and even his appearance changes. Along with grief, a veil falls over the intellect, and a person begins to act savagely, rushing to strike, not refraining even from murder. If unable to do anything, he tears his own clothes, starts hitting himself, begins to utter nonsense, breaks utensils, and sometimes starts hitting an innocent person. In short, he does such things that, if he were to see himself in a state of composure, he would be ashamed. This is the apparent harm; the harm to the heart is even greater. Due to anger, the heart remains filled with malice, rancor, envy, and the fire of revenge; peace and tranquility depart. A person falls into disobedience to Allah, and severs ties with friends, relatives, and believing brothers. Now reflect on the wise advice of the Messenger sallallahu alayhi wa sallam: how many words of wisdom are contained in this short sentence! By acting upon it, a person attains so many benefits and is saved from so many harms.

➍ What does “Do not get angry” mean?
It is evident that anger is a natural thing; it is not possible that anger never arises. In fact, to become angry for the sake of Allah’s religion is praiseworthy, and from it the spirit of jihad is nurtured. Therefore, “Do not get angry” means: do not become angry in those situations where Allah does not like anger.
In such situations, “Do not get angry” has two states:
One is before anger arises, and the other is after anger arises.
Before anger arises, «لَا تَغْضَبْ» means: strive so that anger does not arise, to the extent that not becoming angry becomes a habit. For this, one must adopt those causes by which a person acquires good character, such as forbearance, modesty, acting thoughtfully, bearing excesses, not harming anyone, forgiveness, swallowing anger, and meeting everyone with an open and cheerful face. When these things become habitual, then at the time of distress, due to this habit, a person will be saved from becoming angry.
After anger arises, «لَا تَغْضَبْ» means: do not act upon what anger dictates.
Ibn Hibban rahimahullah, after narrating this hadith, said: “After anger arises, do not do anything from which you have been prohibited.” This means: strive to control your anger, and do not, by following it, commit any act of disobedience to Allah, because the real strong and powerful person is the one who, at the time of anger, controls himself and does not commit any act of disobedience to Allah.
When anger arises, what is the way to remove it? For this, see the explanation of hadith 1396/2 in Bulugh al-Maram.

Takhrij:
«أخرجه البخاري، الأدب، باب الحذر من الغضب، حديث:6116.»©Explanation:
In this hadith, there is an emphasis on avoiding anger.
Many acts of oppression are committed by a person in a state of anger, and later he is often regretful and distressed.
Allamah Ibn al-Teen rahimahullah states that in this hadith, the goodness of this world and the Hereafter have been combined, because in a state of anger, a person becomes devoid of the qualities of gentleness and compassion, becomes a cause of severing ties of kinship, and becomes intent on harming and causing distress to another Muslim.
And these matters become a cause of ruin for a person in this world and the Hereafter.
And if he avoids them, then these very matters become a cause of success and salvation in this world and the Hereafter.
Allamah Khattabi rahimahullah has said that what is meant by avoiding anger is to avoid those causes which lead to anger, because anger itself is a natural and innate matter, and among those causes is arrogance as well.
Some scholars have said that the Messenger of Allah sallallahu alayhi wa sallam said this in view of the temperament of the questioner, that he should not become angry, because he used to become enraged at every little thing.
In Musnad Ahmad, it is mentioned that the questioner was Jariyah ibn Qudamah.
(Musnad Ahmad: 3/484) And in another hadith, it is mentioned that the questioner was Sufyan ibn Abdullah al-Thaqafi.
For further details regarding this, see: (al-Mawsu‘ah al-Hadithiyyah, Musnad al-Imam Ahmad: 25/330, 333)
