Musannaf Ibn Abi Shaybah

Hazrat Abu Bakr bin Ayyash says that I asked Hazrat Ata whether Hazrat Ali (may Allah be pleased with him) used to lead them in Tarawih prayers. He replied that among the distinguished students of Hazrat Ali (may Allah be pleased with him), Hazrat Zadhan, Hazrat Abu Al-Bakhtari, and other individuals used to gather their respective people in the mosque during Ramadan and lead them in prayer.
