Musannaf Ibn Abi Shaybah

Hazrat Abu Khalid says that I saw Ibrahim talking to a man during the sermon on Friday.

Hazrat Urwah bin Zubair did not consider it objectionable if a person, on the day of Jumu'ah, spoke while not listening to the sermon; that is, if the voice was not reaching him.

Hazrat Ismail bin Ibrahim narrates that my father Ibrahim and Hazrat Saeed bin Jubair were conversing during the sermon of Hajjaj bin Yusuf.
