Sheikh at-Toosi mentioned him as one of Imam al-Askari's companions. Ibn Dawud said about him, ‘He is highly praiseworthy.’Ahmad narrated, ‘Abu Ja’far Muhammad bin Ahmad bin Ja’far al- Qummi al-Attar wrote to the Imam (peace be on him) describing us to him. The Imam (a.s.) replied, ‘I read that which you described Abu Hamid (may Allah honor him by His obedience) with and understood his state. May Allah take him to the best end and not cease His favors on him, and may Allah be his guardian.’
