Sayyidina Abu Dharr (RA) reported that Allah’s Messenger (SAW) said, “Your smile before your brother is a sadaqah for you, and your enjoining piety and forbidding evil is a sadaqah. Your guiding one who is lost on the land is a sadaqah for you. Your leading the blind is a sadaqah for you. Your removing from the thoroughfare a stone, a thorn or a bone is for you a sadaqah. And, your filling with your bucket the bucket of your brother is a sadaqah for you.
[Ahmed 21538]
