"The Messenger of Allah ruled that every clan should take part in paying the blood money, and it is not permissible for a freed slave to take a Muslim (other than the one who freed him) as his Mawla (Patron) without the permission (of his former master who set him free)"
أَنَّهُ سَمِعَ جَابِرًا يَقُولُ كَتَبَ رَسُولُ اللَّهِ ﷺ عَلَى كُلِّ بَطْنٍ عُقُولَةً وَلاَ يَحِلُّ لِمَوْلًى أَنْ يَتَوَلَّى مُسْلِمًا بِغَيْرِ إِذْنِهِ
