Hadith 4919
Narrated Abud Darda: 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).
Hadith 4920
Humaid bin Abdur-Rahman quoted his mother as saying: The Prophet ﷺ said: He who forged in order to put things right between two persons did not lie. The version by Ahmad ibn Muhammad and Musaddad has: The liar is not the one who puts things right between people, saying what is good and increasing good.
Hadith 4921
Umm Kulthum, daughter of Uqbah, said: I did not hear the Messenger of Allah ﷺ giving licence for anything people say falsely except in three matters. The Messenger of Allah ﷺ would say: I do not count liar a man who puts things right between people, saying a word by which he intends only putting things right, and a man who says something in war, and a man who says something to his wife says something to his husband.
