Sayyiduna Sa'sa'ah bin Najiyah (may Allah be pleased with him) said: I came to the Messenger of Allah (peace and blessings be upon him) and said: O Messenger of Allah, sometimes I have some surplus (wealth) left over, which I keep aside for a calamity or for a traveller. The Messenger of Allah (peace and blessings be upon him) said: "Give to your mother and father, then to your sister and brother, then to whoever is closest to you, then to whoever is closest to you."
