According to search-discovered classical Islamic scholarship, the principle of 'Intisar' (defending against wrong), rooted in Quran 42:39, establishes the legitimate right of believers to defend themselves when subjected to 'baghy'—oppressive transgression. Ibn Kathir explains this is a praiseworthy characteristic, indicating strength and a refusal to accept humiliation. Al-Qurtubi's analysis further clarifies that this is a permissible act to restore justice. However, this right is immediately contextualized by the subsequent verses, which elevate the virtues of forgiveness and patience. Thus, 'Intisar' is not a mandate for retaliation but a divinely sanctioned option, where the wisdom to choose between justified defense and noble forgiveness is a hallmark of spiritual maturity.
