“I heard the Messenger of Allah ﷺ say: 'Reconciling between Muslims is permissible, except reconciliation that forbids something that is allowed, or allows something that is forbidden.'”  

سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ الصُّلْحُ جَائِزٌ بَيْنَ الْمُسْلِمِينَ إِلاَّ صُلْحًا حَرَّمَ حَلاَلاً أَوْ أَحَلَّ حَرَامًا
