(1) باب الْحَثِّ عَلَى الصَّلاَةِ فِي الْبُيُوتِ وَالْفَضْلِ فِي ذَلِكَ
It was narrated from Sa'd bin Ishaq bin Ka'b bin Ujrah, from his father, that:
His grandfather said: "The Messenger of Allah (ﷺ) prayed Maghrib in the masjid of Banu 'Abdul-Ashhal, and when he finished praying some people stood up and offered Nafl prayers. The Prophet (ﷺ) said: 'You should offer this prayer in your houses.'"
