وعنه قال: كنا بالمدينة فإذا أذن المؤذن لصلاة المغرب ابتدروا السواري، فركعوا ركعتين، حتى إن الرجل الغريب ليدخل المسجد فيحسب أن الصلاة قد صليت من كثرة من يصليهما
When we were in Al-Madinah, the moment the Muadhdhin finished the Adhan of the Maghrib prayer, the people hastened to the pillars of the mosque and performed two Rakah prayer behind them. A stranger coming into the mosque would think that the obligatory prayer had already been performed because of the number of people performing them.
