Wallatheena itha asabahumu albaghyu hum yantasiroon (surah shura: 39)

Tafseer Tafheem-ul-Quran by Syed Abu-al-A'la Maududi

(42:39) who, when a wrong is done to them, seek its redress. *63

Wallazeena izaa asaabahumul baghyu hum yantasiroon

*63) This also is one of the best characteristics of the believers: they do not fall a prey to the tyrants. Their tender heartedness and forgiving nature is not the result of any weakness. They have not been taught to live humbly and meekly like the hermits and ascetics. Their nobility demands that when they are victors they should forgive the errors of the vanquished; when they possess the power, they should avoid vengefulness and when a weak or subdued person happens to commit a mistake they should overlook it; but when a powerful person, drunk with anthorinty, commits violence against them, they should resist and fight him with all their might. A believer is never cowed by a wicked person nor bows to an arrogant man. For such people he proves to be a hard nut which breaks the teeth of those who try to break it.
