From Sahih Muslim (Hadith 2393):
Abu Huraira reported Allah's Messenger (ﷺ) as saying:The poor man (miskin) is not the one who goes round to the people and is dismissed with one or two morsels. and one or two dates. They (the Prophet's Companions) said: Messenger of Allah, then who is miskin? He said: He who does not get enough to satisfy him, and he is not considered so (as to elicit the attention of the benevolent people), so that charity way be given to him. and he does not beg anything from people
