Al-Qasim al-Shami relates: Sahl Ibn al-Hanzaliyyah (may Allah be pleased with him) passed by a man who was praying standing far back from the qiblah (from his sutrah), and Sahl (may Allah be pleased with him) said: "Move forward to your place of prayer, lest Satan cut off your prayer. And I tell you only what I heard from the Messenger of Allah (peace and blessings be upon him)."
