وعن البراء
رضي الله عنه قال: «كنا إذا صلينا خلف رسول الله صلى الله عليه وسلم، أحببنا أن نكون عن يمينه، يقبل علينا بوجهه، فسمعته يقول: «رب قني عذابك يوم تبعث (أو تجمع) عبادك»
Whenever we performed Salat behind the Messenger of Allah (sallallahu alayhi wa sallam), we liked to be on his right side so that his face might turn towards us (at the end of the Salat). One day, I heard Messenger of Allah (sallallahu alayhi wa sallam) supplicating, “O my Rubb! Shield me from Your Torment on the Day when You will gather (or said, ‘resurrect’) Your slaves.”.
