Hadith 10:271
Abu Bakr as-Siddiq reported the Prophet as saying, “One who treats badly those under his authority will not enter paradise.” Tirmidhi and Ibn Majah transmitted it.
وَعَنْ أَبِي بَكْرٍ الصِّدِّيقِ رَضِيَ اللَّهُ عَنْهُ عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: «لَا يَدْخُلُ الْجَنَّةَ سَيِّئُ الْمَلَكَةِ» . رَوَاهُ التِّرْمِذِيُّ وَابْن مَاجَه
