In the name of Allah, the Most Beneficent, the Most Merciful
An-Nawawi records in his book Riyad us-Saliheen:
Allah the Exalted said:
لَّا خَيْرَ فِي كَثِيرٍ مِّن نَّجْوَاهُمْ إِلَّا مَنْ أَمَرَ بِصَدَقَةٍ أَوْ مَعْرُوفٍ أَوْ إِصْلَاحٍ بَيْنَ النَّاسِ
No good is there in much of their private conversation, except for those who enjoin charity or kindness or reconciliation between people.
Surat An-Nisa 4:114
And Allah said:
وَالصُّلْحُ خَيْرٌ
Settlement is best.
Surah An-Nisa 4:128
And Allah said:
فَاتَّقُوا اللَّهَ وَأَصْلِحُوا ذَاتَ بَيْنِكُمْ
Fear Allah and reconcile between yourselves.
Surat Al-Anfal 8:1
And Allah said:
إِنَّمَا الْمُؤْمِنُونَ إِخْوَةٌ فَأَصْلِحُوا بَيْنَ أَخَوَيْكُمْ وَاتَّقُوا اللَّهَ لَعَلَّكُمْ تُرْحَمُونَ
The believers are but brothers, so make reconciliation between your brothers and fear Allah that you may receive mercy.
Surat Al-Hujurat 49:10
Abu Huraira, RadhiAllahu Anhu, reported: The Messenger of Allah, SallAllahu Alayhi Wa Sallam, said:
كُلُّ سُلَامَى مِنْ النَّاسِ عَلَيْهِ صَدَقَةٌ كُلَّ يَوْمٍ تَطْلُعُ فِيهِ الشَّمْسُ قَالَ تَعْدِلُ بَيْنَ الِاثْنَيْنِ صَدَقَةٌ وَتُعِينُ الرَّجُلَ فِي دَابَّتِهِ فَتَحْمِلُهُ عَلَيْهَا أَوْ تَرْفَعُ لَهُ عَلَيْهَا مَتَاعَهُ صَدَقَةٌ قَالَ وَالْكَلِمَةُ الطَّيِّبَةُ صَدَقَةٌ وَكُلُّ خُطْوَةٍ تَمْشِيهَا إِلَى الصَّلَاةِ صَدَقَةٌ وَتُمِيطُ الْأَذَى عَنْ الطَّرِيقِ صَدَقَةٌ
Charity is due upon every joint of the people for every day upon which the sun rises. Being just between two people is charity. Helping a man with his animal and lifting his luggage upon it is charity. A kind word is charity. Every step that you take towards the mosque is charity, and removing harmful things from the road is charity.

Umm Kulthum, RadhiAllahu Anha, reported: The Messenger of Allah, SallAllahu Alayhi Wa Sallam, said:
لَيْسَ بِالْكَاذِبِ مَنْ أَصْلَحَ بَيْنَ النَّاسِ فَقَالَ خَيْرًا أَوْ نَمَى خَيْرًا
He is not a liar who reconciles people by saying something good or inventing something good.

Aisha, RadhiAllahu Anha, reported: The Messenger of Allah, SallAllahu Alayhi Wa Sallam, heard the loud voices of two men in a dispute at the door. One was asking the other to lessen his debt and was pleading with him to show leniency, and the other said, “By Allah, I will not do that!” The Messenger of Allah, SallAllahu Alayhi Wa Sallam, came out to them and he said:
أَيْنَ الْمُتَأَلِّي عَلَى اللَّهِ لَا يَفْعَلُ الْمَعْرُوفَ
Where is the one who swore by Allah that he would not do good?
The man said:
أَنَا يَا رَسُولَ اللَّهِ وَلَهُ أَيُّ ذَلِكَ أَحَبَّ
O Messenger of Allah, it was me. Now he may have what he wanted.
