Mishkat al-Masabih #1822

Abu Dharr reported God’s messenger as saying, “When you smile in your brother’s face, or enjoin what is reputable, or forbid what is objectionable, or direct someone who has lost his way, or help a man who has bad eyesight, or remove stones, thorns and bones from the road, or pour water from your bucket into your brother’s, it counts to you as sadaqa.” Tirmidhi transmitted it, saying this is a gharib tradition.
