Chapter on the Virtue of Mosques and Prayer Within Them, and the Virtue of Congregational Prayer and Its Rulings

From him, from al-Husayn ibn Saeed from Hammad ibn Isa from Muawiyah ibn Wahb who said: I saw Abu Abdillah عليه السلام, peace be upon him, one day enter the ‘Sacred Mosque’ at the time of the afternoon (Asr) prayer. When Imam عليه السلام was still short of reaching the rows, they bowed, so Imam عليه السلام bowed alone and performed the two prostrations, then stood up and continued until Imam عليه السلام reached the rows.
