Sayyiduna Abu al-Darda' (may Allah be pleased with him) narrates: The Prophet (peace and blessings be upon him) said: "Shall I tell you of a deed that is the best and purest in the sight of your Master, that raises your ranks the most, that is better for you than spending gold and silver, and better for you than meeting your enemy, with them striking your necks and you striking their necks? (That thing) is the remembrance of Allah."
Ahmad recorded it, and its chain is hasan (good).
