Hasan al-Hulwānī narrated to us, he said, I heard Shabābah say: ‘Abd ul-Quddūs was narrating to us saying,‘Suwayd bin Aqalah said…’ Shabābah said: ‘And I heard Abd ul-Quddūs saying, ‘The Messenger of Allah, peace and blessings of Allah upon him, prohibited taking a Rawḥ by accident’. [Shabābah] said: ‘So it was said to him, ‘What does this mean?’ said: ‘It means to make an opening in a wall a breeze enter ’.’ Muslim said, I heard Ubayd Allah bin Umar al-Qawārīrī saying, I heard Hammād bin Zayd saying to a man after he sat with Mahdī bin Hilāl for days: ‘What is this salty well [i.e. useless or harmful] which has sprung up in your direction?’ He said: ‘Yes, oh Abā Ismā’īl ’.
