question #3 Sahih al-Bukhari 1172, 1173, Book 19, Hadith 51 : How did the Prophet Muhammad (ﷺ) incorporate light rak’ahs after dawn into his prayer routine?

I offered with the Prophet (ﷺ) two rak`at before the Zuhr and two rak`at after the Zuhr prayer; two rak`at
after Maghrib, `Isha’ and the Jumua prayers. Those of the Maghrib and `Isha’ were offered in his
house. My sister Hafsa told me that the Prophet (ﷺ) used to offer two light rak`at after dawn and it was the
time when I never went to the Prophet.”
