Muhammad ibn Abi Bakr narrated to us, Abd al-Aziz ibn Abd al-Samad narrated to us, Mansur narrated to us, from Abu Wa'il, from Abdullah, that a man came to the Prophet, may Allah bless him and grant him peace, and said: "So-and-so slept through the prayer last night." He said: "Satan urinated in his ear, or his two ears."
