question #1 Sahih al-Bukhari 937, Book 11, Hadith 61 : What is the significance of performing additional rak`at prayers before and after obligatory prayers?

Allah’s Messenger (ﷺ) used to pray two rak`at before the Zuhr prayer and two rak`at after it. He also used to
pray two rak`at after the Maghrib prayer in his house, and two rak`at after the `Isha’ prayer. He never
prayed after Jumua prayer till he departed (from the Mosque), and then he would pray two rak`at at
home.
