Sa‘d b. ‘Ubada told God’s messenger that Umm Sa'd had died and asked him what form of sadaqa was best. When he replied that water was best, he dug a well and said it was for Umm Sa'd.
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.
Abu Sa'id reported God’s messenger as saying,
“If any Muslim clothes a Muslim when he is naked, God will clothe him with some of the green garments of paradise; if any Muslim feeds a Muslim when he is hungry, God will feed him with some of the fruits of paradise; and if any Muslim gives a Muslim drink when he is thirsty, God will give him some of the pure wine which is sealed* to drink.”
Jabir reported God’s messenger as saying,
“Every act of kindness is sadaqa, and kindness includes meeting your brother with a cheerful face and pouring water from your bucket into your brother’s vessel."
