Abu Dawud Book 3, Hadith Number 1622.

Narated By Abdullah ibn Mas’ud : The Prophet (PBUH) 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, Apostle 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.
