From Sahih Muslim (Hadith 2394):
Abu Huraira reported Allah's Messenger (ﷺ) as saying:Miskin is not he who is dismissed with one or two dates, and with one morsel or two morsels. (In fact) miskin is he who abstains (from begging). Read if you so desire (the verse):" They beg not of men importunately)" (ii)
