It is narrated from Sayyiduna al-Bara' (may Allah be pleased with him) that when we prayed behind the Messenger of Allah (peace and blessings be upon him), we liked to stand on his right side so that he would sit facing us. The narrator relates: I heard him (peace and blessings be upon him) reciting: 'Rabbi qini adhabaka yawma tab'athu ibadak' (O Allah, protect me from Your punishment on the Day You resurrect Your servants).
