Sunan Ibn Majah

It was narrated that Abu Hurairah said: “The Messenger of Allah (ﷺ) said: ‘Whoever performs twelve Rak’ah (of Sunnah) each day, a house will be built for him in Paradise: two Rak’ah before Fajr, two Rak’ah before the Zuhr, two Rak’ah after the Zuhr, two Rak’ah, I think he said, before ‘Asr, two Rak’ah after Maghrib, and I think he said two Rak’ah after the ‘Isha’.’”
