Then he said: "(O ꜤIṣām) lighten your burden upon yourself! I ask Allah Almighty for forgiveness for you and for myself." ^[1]

سُبْحٰنَ اللہ! Dear Islamic brothers! Reflect! What beautiful conduct, what excellent character! The person opposite is speaking ill, and Sayyidunā Imam Ḥusayn  رَضِىَ اللّٰهُ عَـنْهُ is supplicating for his forgiveness. This is a very beautiful formula for eliminating hatred and increasing love; we too should adopt this way.

Allah Almighty states in the noble Quran:

اِدْفَعْ  بِالَّتِیْ  ھِیَ  اَحْسَنُ فَاِذَا الَّذِیْ بَیْنَکَ وَ بَیْنَہٗ  عَدَاوَۃٌ کَاَنَّہٗ  وَلِیٌّ حَمِیْمٌ (۳۴)

And, goodness and evil cannot be equal. Repel evil with what is best; then he, between whom and you there is enmity, will become as though he is a close friend.^[2]

In Tafsīr Ṣirāṭ al-Jinān, it is stated:

From this verse, it is known that the religion of Islam has provided Muslims with the loftiest, comprehensive, and most excellent teachings of ethics: repel evil with good, such as enduring patiently when someone causes you distress, demonstrating forbearance and tolerance when someone behaves ignorantly or foolishly, and practicing forgiveness and overlooking when mistreated!^[3]

May Allah Almighty also grant us the ability to forgive and to respond to evil with good.

اٰمِیْنْ بِجَاہِ خاتَمِ النَّبِیّٖن صلَّی اللہُ عَلَیْہ ِوَاٰلِہٖ وَسَلَّمَ
