Sayyiduna Abu Dharr Ghifari (may Allah be pleased with him) narrates: The Prophet Muhammad (peace and blessings be upon him) said: "Your smiling at your brother is charity for you. Your enjoining good and forbidding evil is charity. Your guiding a man who is lost on the land is charity for you, or showing the way to a person whose eyesight is weak is charity for you. And your removing a thorn, stone, or bone from the path is charity for you. And your pouring from your bucket into your brother’s bucket (is charity for you)."
