Mariyyah was present at the time of the birth of Imam Muhammad Ibn al-Hasan ('aj), meaning she was alive in the year 255 A.H. No information was found on her biography or family. Her name has only been found from the tradition which Shaykh al-Saduq has related.

She related traditions from Imam al-Mahdi ('aj), and al-Sayyari has related traditions from her. Shaykh al-Saduq based on his documents has related from al-Sayyari that he said, "Nasim and Mariyyah came to me and told me this tradition: When Imam al-Mahdi ('aj) was born he sat on his two knees and raised his pointer finger toward the sky. He sneezed and said, 'Praise and thanks be to God who is the Lord of the two worlds, and greetings upon Muhammad and his descendants. The oppressors have claimed that the existence of the Proof of God (Hujjah) is illogical. If they give me a chance to speak, all doubt will be removed.'"1
