It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that he said: "The Messenger of Allah (peace and blessings be upon him) prostrated on a muddy day, so much so that I could see the traces of it (the mud) on his (peace and blessings be upon him) forehead and the tip of his nose."
No one narrated this hadith from Imam al-Awza'i (may Allah have mercy on him) except Suwayd (may Allah have mercy on him), and Zuhayr bin Abbad (may Allah have mercy on him) is alone in narrating it from him.
