All the famous men of letters belonging to this class are attached to Shi'ism. Nabigha Ju'di, for instance, took part in the battle of Siffin on the side of 'Ali (a.s.) and the "Rajaz" (rousing verses) that he composed for the occasion are very well known; 'Urwah ibn Zayd al-Khayl was also with the Holy Imam (a.s.) in the battle of Siffin (see al-Aghani).
'Allamah al-Dhahabi ameandika katika kumwelezea Al-Suddi kuwa yeye alidaiwa kuwa Mshi'a na Husayn ibn Waqid al-Muruzi ametaja kuwa yeye amemsikia akiwalaumu Abu Bakr na 'Umar, lakini pamoja na kujua ukweli huu, Al-Thawri, Abu Bakr ibn 'Ayyash na wengineo wamezichukua na kuzipokea riwaya zake, na Imama Muslim, Tirmidhi, Abu Dawud, Ibn Majah, na Nasa'i wameziandika katika vitabu vyao vijulikanavyo kwa jina la Sahih kwa kuunga maoni yao.
