The Messenger of Allah ﷺ said, "Whoever prays twelve units of prayer, Allah will build for him a house in Paradise. Four units before the noon prayer, two units after the noon prayer, two units before the afternoon prayer, two units after the sunset prayer, and two units before the dawn prayer."
أخبرنا الربيع بن سليمان قال أنبأنا أبو الأسود قال حدثني بكر بن مضر عن ابن عجلان عن أبي إسحق الهمداني عن عمرو بن أوس عن عنبسة بن أبي سفيان
أن رسول الله ﷺ قال اثنتا عشرة ركعة من صلاهن بنى الله له بيتا في الجنة أربع ركعات قبل الظهر وركعتين بعد الظهر وركعتين قبل العصر وركعتين بعد المغرب وركعتين قبل صلاة الصبح
Sahih. Muslim collected it in the Book of the Prayer of the Traveler, chapter on the merit of the regular sunnah prayers before and after the obligatory prayers and the statement of their number, hadith 728, from the hadith of Amr bin Aws, in abridged form. It is also in Sunan al-Kubra, hadith 1472, where Nasai said, "Zuhayr differed with him, narrating it from Abu Ishaq from Musayab bin Rafi without raising the hadith to the Prophet." This defect is not a serious flaw, and the hadith has corroborating narrations.
