Mishkat al-Masabih 13 Marriage كتاب النكاح 286

وَعَنْ أَبِي هُرَيْرَةَ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: «أَلَا أُنَبِّئُكُمْ بِشِرَارِكُمُ؟ الَّذِي يَأْكُلُ وَحْدَهُ وَيَجْلِدُ عَبْدَهُ وَيَمْنَعُ رِفْدَهُ» . رَوَاهُ رزين

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.
