What did the Prophet Muhammad (saw) say about those who are unable to beg?
  Abu Huraira reported Allah's Messenger (may peace be upon him) 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. 273).
