Abu Bakr narrated to us, he said: Waki’ narrated to us, he said: Hammad ibn Salamah narrated to us, from Thabit al-Bunani, from Anas ibn Malik, who said: The companions of the Prophet, may God bless him and grant him peace, used to pray in the paths of al-Ahwaz. And Anas ibn Malik used to pray in a servant's passageway.
