عَنْ أَبِي هُرَيْرَةَ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ ”مَنْ تَوَلَّى قَوْمًا بِغَيْرِ إِذْنِ مَوَالِيهِ فَعَلَيْهِ لَعْنَةُ اللَّهِ وَالْمَلَائِكَةِ وَالنَّاسِ أَجْمَعِينَ لَا يَقْبَلُ اللَّهُ مِنْهُ يَوْمَ الْقِيَامَةِ عَدْلًا وَلَا صَرْفًا وَالْمَدِينَةُ حَرَامٌ فَمَنْ أَحْدَثَ فِيهَا أَوْ آوَى مُحْدِثًا فَعَلَيْهِ لَعْنَةُ اللَّهِ وَالْمَلَائِكَةِ وَالنَّاسِ أَجْمَعِينَ لَا يَقْبَلُ اللَّهُ مِنْهُ يَوْمَ الْقِيَامَةِ عَدْلًا وَلَا صَرْفًا وَذِمَّةُ الْمُسْلِمِينَ وَاحِدَةٌ يَسْعَى بِهَا أَدْنَاهُمْ فَمَنْ أَخْفَرَ مُسْلِمًا فَعَلَيْهِ لَعْنَةُ اللَّهِ وَالْمَلَائِكَةِ وَالنَّاسِ أَجْمَعِينَ لَا يَقْبَلُ اللَّهُ مِنْهُ يَوْمَ الْقِيَامَةِ عَدْلًا وَلَا صَرْفًا“
It is narrated from Sayyiduna Abu Hurairah, may Allah be pleased with him, that the Noble Prophet, peace and blessings be upon him, said: Whoever appoints another as his master without the permission of his own masters, upon him is the curse of Allah, the angels, and all people; on the Day of Resurrection, Allah will not accept any obligatory or supererogatory act of worship from him. Madinah is a sanctuary; whoever commits an innovation or a sinful act here, or gives refuge to an innovator or sinner, upon him is the curse of Allah, the angels, and all people; on the Day of Resurrection, Allah will not accept any obligatory or supererogatory act of worship from him. The protection of all Muslims is equal; any ordinary Muslim can grant protection to a non-Muslim. Whoever breaks the covenant of a Muslim, upon him is the curse of Allah, the angels, and all people, and on the Day of Resurrection, Allah will not accept any obligatory or supererogatory act of worship from him.
