Narrated Thabit ibn Qays ibn Shammas: The Messenger of Allah (ﷺ) entered upon Thabit ibn Qays. The version of Ahmad (ibn Salih) has: When he was ill He (the Prophet) said: Remove the harm, O Lord of men, from Thabit ibn Qays ibn Shammas. He then took some dust of Bathan, and put it in a bowel, and then mixed it with water and blew in it, and poured it on him. Abu Dawud said: Ibn al-Sarh said: Yusuf bin Muhammad is correct (and not Muhammad bin Yusuf)
