Musannaf Ibn Abi Shayba 3:2859

Hashim narrated to us, he said: Abd al-Hamid ibn Ja'far al-Ansari informed us, with an isnad that I do not memorize: They used to come on the day of Friday, then they would sit around the pulpit. Then they would turn toward the Prophet, may Allah bless him and grant him peace, with their faces.
