Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) said: "It is part of the Sunnah that when a man invites his brother (to a meal), he should get up and walk with him (when he takes leave) until he goes out (of the house)."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Ikrimah (may Allah have mercy on him) except Ubayd bin Hammam, and no one narrated it from Ubayd except Abu Sayfi; al-Salt is alone in narrating it."
