Ammat Muhammad Ibn Marid (Ziyad) was one of the transmitters of traditions from Imam al-Sadiq ('a), but no other information was found about her.1 In the books about the transmitters of traditions she has been listed as 'Ammat Muhammad Ibn Marid in one place and 'Ammat Muhammad Ibn Ziyad in another. Ibn Qawlawayh has mentioned both names for her. However, when these two traditions and their chains of transmission are carefully studied it seems they are from one person.

She has related traditions from Abu 'Abdullah al-Sadiq ('a), and Muhammad Ibn Marid (Ziyad) has related traditions from her.

Ibn Qawlawayh relates from his father according to his documents from Isa Ibn Sulayman from Muhammad Ibn Marid (Ziyad) from his aunt as saying, "I heard Imam al-Sadiq ('a) state, 'The dust from the grave of al-Husayn ('a) heals, and it keeps a person from fear and worrying."2

• 1. Ibn Qawlawayh relates two traditions which are similar to each other with different chains of transmission from 'Isa Ibn Sulayman from Muhammad Ibn Ziyad and Muhammad Ibn Marid from his uncle Muhammad Ibn Ziyad and Muhammad Ibn Marid. (Kamil al-Ziyarat, pp. 278 and 279) It appears these two traditions are actually one in the same, and the names also refer to one person.
