It is narrated from Sayyiduna Samurah bin Jundub (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Begging from people is a wound with which a man wounds his own face. So whoever wishes may preserve his face (from this mark), and whoever wishes may leave it."
