Musannaf Ibn Abi Shaybah

Hazrat Musa bin Muslim says that I was with Ibrahim Taimi, Ibrahim Nakha'i, Hazrat Zar, and Hazrat Salamah bin Kuhail on the day of Jumu'ah. Hazrat Zar and Hazrat Taimi mentioned the day of Jumu'ah, so they performed four rak'ahs of Jumu'ah at that very place; they were hiding out of fear of (the tyrant Hajjaj bin Yusuf).
