2. Ali ibn Ibrahim has narrated from his father from Ibn Abi ‘Umayr from Muhammad ibn Ishaq who has said the following: “I once asked abu al-Hassan , about the case of a man who has a castrated slave; if he can go to his women and provide them water for wudu and look at their hairs. He (the Imam) said, ‘No, he can do so.”’
