“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.'” (Using translation from Ibn Mājah 2353)   

قَالَ رَسُولُ اللَّهِ ﷺ «الصُّلْحُ جَائِزٌ بَيْنَ الْمُسْلِمِينَ إِلَّا صُلْحًا أَحَلَّ حَرَامًا أَوْ حَرَّمَ حَلَالًا»  

The Prophet ﷺ said: Shall I not inform you of something more excellent in degree than fasting, prayer and almsgiving (sadaqah)? The people replied: Yes, Prophet of Allah! He said: It is putting things right between people, spoiling them is the shaver (destructive). (Using translation from Abū Dāʾūd 4919)   

عَنْ رَسُولِ اللَّهِ ﷺ قَالَ «أَلَا أُخْبِرُكُمْ بِأَفْضَلَ مِنْ دَرَجَةِ الصِّيَامِ وَالْقِيَامِ؟ » قَالُوا بَلَى يَا رَسُولَ اللَّهِ قَالَ «إِصْلَاحُ ذَاتِ الْبَيْنِ وَفَسَادُ ذَاتِ الْبَيْنِ هِيَ الْحَالِقَةُ»  

[Machine] Indeed, the Prophet ﷺ said: "Whoever goes to such and such a place or does such and such a thing, the young men would rush to it while the elders remain under the flags." So when Allah granted them victory, they came seeking what the Prophet ﷺ had designated for them. The elders said to them, "Do not take it before us, for we were your substitute." Then Allah revealed this verse to them: "So fear Allah and amend that which is between you."  

أَنَّ النَّبِيَّ ﷺ قَالَ «مَنْ أَتَى مَكَانَ كَذَا وَكَذَا أَوْ فَعَلَ كَذَا وَكَذَا * فَتَسَارَعَ إِلَيْهِ الشُّبَّانُ وَبَقِيَ الشُّيُوخُ تَحْتَ الرَّايَاتِ» فَلَمَّا فَتَحَ اللَّهُ عَلَيْهِمْ جَاءُوا يَطْلُبُونَ مَا قَدْ جَعَلَ لَهُمُ النَّبِيُّ ﷺ فَقَالَ لَهُمُ الْأَشْيَاخُ لَا تَذْهَبُونَ بِهِ دُونَنَا فَإِنَّا كُنَّا رِدْءًا لَكُمْ فَأَنْزَلَ اللَّهُ هَذِهِ الْآيَةَ {فَاتَّقُوا اللَّهَ وَأَصْلِحُوا ذَاتَ بَيْنِكُمْ}
