Mukhtasar Bukhari (Abridged) 1184 — One who reconciles between people

Narrated from Sayyidah Umm Kulthum bint Uqbah (may Allah be pleased with her) that she heard the Messenger of Allah (peace and blessings of Allah be upon him) say: "The person who conveys something good among people to make peace between them, or says any other good thing in this regard, is not a liar."
