He who took the freed slave as his ally without the consent of his previous master, there is upon him the curse of Allah and that of His angels and that of the whole mankind, and there will not be accepted from him his obligatory acts or supercrogatory acts on the Day of Resurrection. This hadith is narrated through the same chain of transmitters, but with a slight change of words.  

عَنِ النَّبِيِّ ﷺ قَالَ مَنْ تَوَلَّى قَوْمًا بِغَيْرِ إِذْنِ مَوَالِيهِ فَعَلَيْهِ لَعْنَةُ اللَّهِ وَالْمَلاَئِكَةِ وَالنَّاسِ أَجْمَعِينَ لاَ يُقْبَلُ مِنْهُ يَوْمَ الْقِيَامَةِ عَدْلٌ وَلاَ صَرْفٌ وَحَدَّثَنِيهِ إِبْرَاهِيمُ بْنُ دِينَارٍ حَدَّثَنَا عُبَيْدُ اللَّهِ بْنُ مُوسَى حَدَّثَنَا شَيْبَانُ عَنِ الأَعْمَشِ بِهَذَا الإِسْنَادِ غَيْرَ أَنَّهُ قَالَ وَمَنْ وَالَى غَيْرَ مَوَالِيهِ بِغَيْرِ إِذْنِهِمْ
