As for what was narrated by Muhammad bin Ahmad bin Yahya, from Sahl bin Ziyad, from Ali bin Al-Hakam, from Aban bin Uthman, from Abu Al-Qasim, from Abu Abdullah عليه السلام, who said: I asked Imam عليه السلام: 'A man wants to relieve himself, and he is wearing a ring with the name of Allah سبحانه وتعالى, the Exalted, on it.' Imam عليه السلام said: 'I do not like that.' I asked: 'What if it has the name Muhammad صلى الله عليه وعلى آله وسلم on it?' Imam عليه السلام said: 'There is no harm in that.'
