“Once we asked Abu ‘Abd Allah (a.s.), saying, ‘We pray to Allah to keep our souls in service for your cause, is it undesirable to write on one’s ring something other than one’s name and the name of one’s father?’ He (the Imam) said, ‘The writing on my ring says, ‘Allah is the Creator of all things’. On the ring of my father, Muhammad ibn Ali (a.s.), who was the best Muhammadi, I saw with my own eyes, the writing said, ‘All glory belongs to Allah. ’ On the ring of Ali ibn al-Husayn (a.s.), the writing said, ‘All praise belongs to Allah, the most High, the most Great.’ On the ring of al-Hassan and al-Husayn (a.s.) the writing said, ‘Allah is sufficient for me.’ On the ring of ’Amir al-Mu’minin (a.s.), the writing said, ‘Allah is the owner’.’”
