It is narrated from the Mother of the Believers, Sayyidah Aishah (may Allah be pleased with her), that the Messenger of Allah (peace and blessings be upon him) said: "Whoever goes in uninvited to a people for food and eats his fill there has eaten what is unlawful."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated these two hadiths from Rawh bin al-Qasim except Yahya bin Khalid; Baqiyyah is alone in narrating both of them."
