Narrated from him from Muhammad ibn al-Husayn from al-Hajjal from Tha’labah ibn Maymun from Mu’awiyah ibn ‘Ammar from Abu Abdillah عليه السلام, who said: I said (to Imam عليه السلام): "A man stands in prayer, and then after finishing he notices that he had deviated from the qiblah to the right or to the left." Imam عليه السلام said: "His prayer is valid. What lies between the East and the West is qiblah."
