Salim narrated on the authority of his father (RA) that Allahs Messenger ﷺ entered the House along with Usama bin Zaid, Bilal (RA) and Uthman bin Talha. They closed the door from within, and, as they opened it, I was the first to get into it and meet Bilal (RA) , and I asked him: Did Allahs Messenger ﷺ observe prayer in it? He said: Yes, he observed prayer between these two Yemenite pillars (pillars situated towards the side of Yemen).
