It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "When one of you finds a louse in the mosque, let him bury it (in the earth there) or remove it away from himself."
Imam al-Tabarani (may Allah have mercy on him) said: No one narrated these two hadith from Ziyad (may Allah have mercy on him) except Yusuf (may Allah have mercy on him), and his son is alone in narrating them from him.
