Sayyiduna Abu Hurayrah (may Allah be pleased with him) said that the Messenger of Allah (peace and blessings be upon him) said: "The needy person is not the one who is turned away by one or two dates, or by one or two morsels; the needy person is only the one who refrains from asking. Recite, if you wish: 'They do not ask people persistently' [Surah al-Baqarah: 273]."
