It was narrated from ‘Abdullah bin ‘Umar that the Messenger of Allah صلی اللہ علیہ وآلہ وسلم entered the Ka’bah with Usamah bin Zaid, Bilal and ‘Uthman bin Talhah Al-IIajabI, and locked the door behind him. ‘Abdullah bin ‘Umar said: “I asked Bilal when he came out: ‘What did the Messenger of Allah صلی اللہ علیہ وآلہ وسلم do?’ He said: ‘He stood with one pillar to his left, two pillars to his right and three pillars behind him — at that time the House stood on six pillars — and he prayed with approximately three forearm’s lengths between him and the wall.” (Sahih)
