What are the four rak'ahs that the Prophet (peace and blessings be upon him) used to maintain after the sun passed its zenith?

Question:
In the name of Allah, the Most Gracious, the Most Merciful. Praise be to Allah, Lord of the worlds, and may peace and blessings be upon the noblest of the prophets and messengers, our Prophet Muhammad, and upon his family and all his Companions. May Allah bless you, Honorable Shaykh, and benefit us with your knowledge, and may Allah reward you with the best reward for us and for the Muslims. The questioner asks: What are the four rak'ahs that the Prophet (peace and blessings be upon him) used to maintain after the sun passed its zenith? Are they the four rak'ahs before Dhuhr, or something else?

Answer:
(peace and blessings be upon him) said: "Whoever prays four rak'ahs before Dhuhr, Allah will build for him a house in Paradise." The narrator mentioned the rawatib (regular voluntary prayers) of Dhuhr; Dhuhr has a rawatib before it and a rawatib after it. Yes. The minimum rawatib for Dhuhr is two rak'ahs before it and two rak'ahs after it; this is the minimum. The maximum is four rak'ahs before Dhuhr and four rak'ahs after Dhuhr; this is the most complete. And this is not done except after the time has entered, the entry of the time of Dhuhr.
