Hadith 10:286
Abu Huraira reported God’s Messenger as saying, “Let me tell you who your evil ones are. They are those who eat alone, beat their slaves, and withhold their help.” Razin transmitted it.
وَعَنْ أَبِي هُرَيْرَةَ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: «أَلَا أُنَبِّئُكُمْ بِشِرَارِكُمُ؟ الَّذِي يَأْكُلُ وَحْدَهُ وَيَجْلِدُ عَبْدَهُ وَيَمْنَعُ رِفْدَهُ» . رَوَاهُ رزين
