9. Ali ibn Ibrahim has narrated from his father from ibn al-Mughirah who has said the following: “I once asked abu al-Hassan , ’How is washing oneself after using the toilet done? 5 He (the Imam) said,

‘It is not clean as long as something is there.’ I then asked, ‘What happens if everything there is washed clean but smell is there?’ He (the Imam) said, ‘Smell is not a thing that can be seen.’”
