Ibn Umar (RA) reported: Allahs Messenger, ﷺ entered the House, and Usama, Bilal (RA) and Uthman bin Talha were with him, and they kept the door closed for a considerable time. Then it was opened and I was the first to enter the House and meet Bilal (RA) , and I said: Where did Allahs Messenger ﷺ observe prayer? He said: Between these two front pillars. I, however, forgot to ask him the number of rakahs that he observed.
