Qasim Rahimahullah narrates: A man passed by Abu Darda (RA) in Damascus when he was planting a tree and said to Abu Darda (RA): Are you also doing a (worldly) work, though you are a Sahabi (companion) of Rasulullah (peace and blessings be upon him)? He said: Don't hasten to blame me; I heard Rasulullah saying: Never did a man plant a sapling (a young tree), and then a man, or any other creation of Allah Glory to Him, ate (or benefited) from it, except that it becomes a Sadaqah (charity) for the planter.
