It was narrated from Sad bin Ishaq bin Kab bin Ujrah, from his father, that: His grandfather said: "The Messenger of Allah (صلی اللہ علیہ وسلم) prayed Maghrib in the masjid of Banu Abdul-Ashhal, and when he finished praying some people stood up and offered Nafl prayers. The Prophet (صلی اللہ علیہ وسلم) said: You should offer this prayer in your houses."
