Hadith 5092
Sayyidah Umm Darda’ (may Allah be pleased with her) narrates from Sayyiduna Abu Darda’ (may Allah be pleased with him) that the Prophet Muhammad (peace and blessings be upon him) said: “Shall I not inform you of an action that is superior in rank to (optional) fasting and prayer?” The people said: “Yes, O Messenger of Allah (peace and blessings be upon him)!” The Prophet (peace and blessings be upon him) said: “Reconciling between people, and creating discord among people is the shaver (i.e., a thing that destroys).”
