“Do not become angry.”
The second cause of anger is anger for the sake of Allah: when a person sees someone violating the sanctities of Allah, he is stirred to jealousy for the religion of Allah and to ardor on its behalf. This kind of anger is praiseworthy, and the one who feels it will be rewarded, for it was the practice of the Messenger of Allah ﷺ and it falls under the Almighty’s words: “Whoever venerates the sacred ordinances of Allah—that is best for him in the sight of his Lord” (al-Ḥajj 22:30), and: “That, and whoever magnifies the symbols of Allah—it is surely from the piety of hearts” (al-Ḥajj 22:32). To venerate Allah’s symbols and sanctities is to regard them as great and to view any affront to them as grave, so that one becomes angry and rises to avenge them by doing what he has been commanded—enjoining right, forbidding wrong, and so forth.
The author next cites another verse: “If you help Allah, He will help you and make your feet firm” (Muḥammad 47:7). Helping Allah here means helping His religion, for Allah Himself needs no help—He is independent of all else. Rather, the help intended is support for the religion of Allah: protecting it, defending it, feeling vexed when it is violated, and every other means of upholding the Law.
Included in this is fighting in the path of Allah so that the word of Allah remains supreme; this too is a form of helping Allah. Allah has promised those who help Him two things: “He will help you and make your feet firm”—He will grant you victory over your enemies and keep your feet steadfast upon His religion so that you do not falter. Reflect, then: if we help Allah once, He rewards us twice—“He will help you…"
