question #3 Sahih al-Bukhari 504, Book 8, Hadith 151 : What significance does the location of the Prophet’s (ﷺ) prayer inside the Ka`ba hold?

The Prophet (ﷺ) entered the Ka`ba along with Usama bin Zaid, `Uthman bin Talha and Bilal and remained
there for a long time. When they came out, I was the first man to enter the Ka`ba. I asked Bilal
“Where did the Prophet (ﷺ) pray?” Bilal replied, “Between the two front Pillars.”
