As for Uyaynah, he took his document and came to the Prophet (ﷺ) at his home, and said to him: Muhammad, do you see me? I am taking a document to my people, but I do not know what it contains, just like the document of al-Mutalammis. Mu'awiyah informed the Messenger of Allah (ﷺ) of his statement.
Thereupon the Messenger of Allah (ﷺ) said: He who begs (from people) when he has sufficient is simply asking for a large amount of Hell-fire. (An-Nufayl (a transmitter) said elsewhere: "embers of Hell".)
They asked: Messenger of Allah, what is a sufficiency? (Elsewhere an-Nufayl said: What is a sufficiency which makes begging unfitting?)
He replied: It is that which would provide a morning and an evening meal. (Elsewhere an-Nufayl said: It is when one has enough for a day and night, or for a night and a day.) He (an-Nufayl) narrated to us this tradition briefly in the words that I have mentioned.
