وَعَن عِمْران بن حُصَينٍ
أَنَّ غُلَامًا لِأُنَاسٍ فُقَرَاءَ قَطَعَ أُذُنَ غُلَامٍ لِأُنَاسٍ أَغْنِيَاءَ فَأَتَى أَهْلُهُ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَقَالُوا: إِنَّا أُنَاسٌ فُقَرَاءُ فَلَمْ يَجْعَلْ عَلَيْهِمْ شَيْئًا
Imran ibn Husayn told that when the slave of some poor people cut off the ear of a slave of some rich people, and his people came to the Prophet (sallallahu alayhi wa sallam) telling him that they were poor, he imposed no compensation on them. Abu Dawud and Nasai transmitted it.
