It was narrated that Ibn ‘Umar said: “The Messenger of Allah صلی اللہ علیہ وآلہ وسلم entered the House, accompanied by Al-Fadi bin ‘Abbas, Usamah bin Zaid, ‘Uthman bin Talhah and Bilal. They shut the door, and he stayed there for as long as Allah willed, then he came out.” Ibn ‘Umar said: “The first one whom I met was Bilal, and I said: ‘Where did the Prophet pray?’ He said: ‘Between the two columns.” (Sahih)
