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
مسند امام احمد بن حنبل · Hadith 5051
It was narrated that Ibn Umar said: I heard the Messenger Allah (PBUH) say: "Whoever beats a slave without him having done anything to deserve it, or slaps him his expiation is to manumit him.”
