It is narrated from Sayyiduna al-Talibb (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Hospitality is three days; whatever is beyond that is charity."
Imam al-Tabarani (may Allah have mercy on him) said: "This hadith is not narrated from al-Talibb (may Allah be pleased with him) except with this chain; Ghalib bin Hajrah is alone in narrating it."
