that a man said to the Prophet ﷺ, “Give me advice.” He replied, “Do not become angry.” What is meant here is twofold:
First: he is advising the man to adopt the means that lead to good character—such as forbearance, deliberation, modesty, endurance, refraining from harm, pardoning, overlooking, suppressing rage, and the like. When the soul is molded by these traits and they become second nature, they will automatically repel anger whenever its causes arise.
Second: he is instructing him not to act on the dictates of anger should it seize him; rather, he must strive against himself to refrain from carrying it out and from doing what anger commands. For when anger takes hold of a human being, it becomes his commander and forbids whatever it wishes. Concerning this Allah, Exalted is He, says: “When Moses’ anger subsided…” (al-A‘raf 7:154).
4 – The virtue of forbearance: Allah the Most High says, “Those who suppress their anger” (Al ‘Imran 3:134), and He says, “and when they are angered, they forgive” (al-Shura 42:37).
Abu Dawud (4777) and al-Tirmidhi (2021)—who graded it sound—recorded on the authority of Mu‘adh ibn Anas al-Juhani that the Messenger of Allah ﷺ said: “Whoever suppresses his rage while able to act upon it, Allah will call him before all of creation and allow him to choose whichever of the wide-eyed maidens he wishes.”
Reports and wise sayings transmitted from the scholars and sages on this subject are exceedingly plentiful.
