Arabic (Original)
حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ حَدَّثَنَا شُعْبَةُ عَنْ فِرَاسٍ سَمِعْتُ ذَكْوَانَ يُحَدِّثُ عَنْ زَاذَانَ عَنِ ابْنِ عُمَرَ قَالَ سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ مَنْ ضَرَبَ غُلَامًا لَهُ حَدًّا لَمْ يَأْتِهِ أَوْ لَطَمَهُ فَإِنَّ كَفَّارَتَهُ أَنْ يُعْتِقَهُ.
English Translation
Muhammad ibn Ja'far narrated to us: Shu'bah narrated to us, from Firas: I heard Dhakwan narrate, from Zadhan, from Ibn Umar, who said: I heard the Messenger of Allah, peace and blessings be upon him, say: Whoever strikes his slave with a punishment he has not earned, or slaps him, then his atonement is to free him.
