Urwah bin Muhammad bin Atiyyah (may Allah have mercy on him) says: My father told me, on the authority of my grandfather, that he said: I came to the Messenger of Allah (peace and blessings be upon him) among some people of (Banu) Sa'd bin Bakr, and I was the youngest of the group, so they left me behind with their belongings and tents. Then they came to the Messenger of Allah (peace and blessings be upon him) and had their needs fulfilled. Then he (peace and blessings be upon him) said: "Is anyone of you still remaining?" They said: O Messenger of Allah, there is a boy from among us whom we left behind at our tents. So he (peace and blessings be upon him) ordered them to send me to him (peace and blessings be upon him). They came to me and said: "Answer the call of the Messenger of Allah (peace and blessings be upon him)." So I came to him (peace and blessings be upon him), and when he (peace and blessings be upon him) saw me he said: "Allah has made you self-sufficient, so do not ask people for anything." And he said: "The giving hand is the upper one, and the lower hand is the one that receives; and indeed, concerning Allah's wealth, it will be asked about and it will be given." He says: Then the Messenger of Allah (peace and blessings be upon him) spoke to me in our own dialect.
