11. Muhammad ibn al-Hassan has narrated from Sahl from Musa ibn al-Qasim from ‘Amr ibn Sa‘id from Musaddiq ibn Sadaqah from ‘Ammar who has said the following: “I once asked abu ‘Abd Allah عليه السلام, ‘A man wants to wash himself clean after using toilet. How should he sit?’ He (the Imam) said, ‘He sits just as he does when defecating.’ He (the Imam) then said, ‘He only needs to wash the outside and not the inside.’”
