عَنْ أَنَسٍ رَضِيَ اللَّهُ عَنْهُ ، قَالَ : قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ : انْصُرْ أَخَاكَ ظَالِمًا أَوْ مَظْلُومًا ، قَالُوا : يَا رَسُولَ اللَّهِ ، هَذَا نَنْصُرُهُ مَظْلُومًا ، فَكَيْفَ نَنْصُرُهُ ظَالِمًا ؟ قَالَ : تَأْخُذُ فَوْقَ يَدَيْهِ(بُخاری:۲۴۴۴)
Translation
Hazrat Anas (R.A) said that the Holy Prophet (PBUH) said, help your brother whether he is an oppressor or oppressed. The companions submitted, O Messenger of Allah! We can help the oppressed. But how do we help the oppressor? He (PBUH) said, hold his hand from oppression (this is his help).
