question #1 Sahih Muslim 525b, Book 5, Hadith 17 : What was the initial direction of prayer for Muslims before it was changed to the Ka’ba?

I heard al-Bara’ saying: We prayed with the Messenger of Allah (ﷺ) (with our faces) towards Bait-ul-Maqdis for sixteen months or seventeen months. Then we were made to change (our direction) towards the Ka’ba.
