Musannaf Ibn Abi Shaybah

Hazrat Ata states that during the afternoon of Wuquf-e-Arafah, the recitation in Zuhr and Asr prayers will not be done aloud.

It is narrated from Ibn Jurayj that Ibrahim bin Hisham stood on the day of Arafah (during Hajj) which was a Friday, and began reciting (Qur'an) aloud. Salim gestured with his hand and said: "Hey! Be silent."

Hazrat Mujahid or Hazrat Tawus state that the Imam, during the afternoon of the standing at Arafah, even if it is on a Friday, will not recite aloud.

It is also narrated in the same way from Hazrat Zuhri, and he states that this is also the opinion of Hazrat Sufyan.

Hazrat Zuhri says that the Imam will not recite aloud (jahran) in the Zuhr and Asr prayers during the standing at Arafah.
