A servant of some poor people cut off the ear of the servant of some rich people. His people came to the Prophet ﷺ and said: Messenger of Allah! we are poor people. So he imposed no compensation on them. (Using translation from Abū Dāʾūd 4590)   

أَنَّ عَبْدًا لِأُنَاسٍ فُقَرَاءَ قَطَعَ يَدَ غُلَامٍ لِأُنَاسٍ أَغْنِيَاءَ فَأَتَى أَهْلُهُ النَّبِيَّ ﷺ فَقَالُوا يَا رَسُولَ اللَّهِ إِنَّهُ لِأُنَاسٍ فُقَرَاءَ؟ «فَلَمْ يَجْعَلْ عَلَيْهِ النَّبِيُّ ﷺ شَيْئًا»
