The Prophet (ﷺ) said: He who begs (from people) when he is affluent will come on the Day of Resurrection with scrapes, scratchings, or lacerations on his face. He was asked: What constitutes affluence, Messenger of Allah? He replied:It is fifty dirhams or its value in gold.

The narrator Yahya said: Abdullah ibn Sufyan said to Sufyan: I remember that Shu'bah does not narrate from Hakim ibn Jubayr. Sufyan said: Zubayr transmitted to us this tradition from Muhammad ibn AbdurRahman ibn Yazid.
Sunan Abi Dawud Book 9, Hadith 71
← Previous Hadith Ziyad, or some other governor, sent Imran ibn Husayn to collect sadaqah (i.e. zakat). When he returned, he asked Imran: Where is the property? He replied: Did you send me to bring the property? We collected it from where we used to collect in the lifetime of the Messenger of Allah (ﷺ), and we spent it where we used to spend during the time of the Messenger of Allah (ﷺ).

Sunan Abi Dawud Book 9, Hadith 70 Next Hadith → A man from Banu Asad said : I and my family alighted at Baqi al-Gharqad. My wife said to me : Go the Messenger of Allah(ﷺ) and beg something from him for our eating, and made a mention of there need. So I went to the Messenger of Allah(May peace be upon him). I found with a man who was begging from him and he was saying to him: I have nothing to give you. The man turned away from him in anger while he was saying: By my life, you give anyone you wish. The Messenger of Allah(May peace be upon him) said : He’s anger with me, for I have nothing to give him. If any of you begs when he has an Uqiyah or its equivalent, he has begged immoderately. The man of Banu Asad said : So I said : The she camel of ours is better than an uqiyah, while an uqiyah is equivalent to 40 Dirhams. I therefore returned and did not beg from him. Afterwards some barley and raisins where brought to the Messenger of Allah (May peace be upon him). He gave us a share from them (or as he reported)till Allah, the Exalted, made us self-sufficient(i.e well off).

Abu Dawud said: Al-Thawri narrated it as Malik narrated.
