It is narrated from Sayyiduna Sa'd bin Abi Waqqas (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Keep your courtyards clean, for the Jews do not keep their courtyards clean."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from al-Zuhri except Ibrahim, and no one narrated it from Ibrahim except Abu Dawud; Zayd bin Akhzam is alone in narrating it."
