Salim b. Abdullah reported his father (Allah be pleased with him) saying:
I saw Allah's Messenger ( صلی اللہ علیہ وسلم ) entering the Ka'ba, and Usama b. Zaid, Bilal and 'Uthman b. Talha were along with him, but none (else) entered therein along with them. Then the door was closed for them from within. 'Abdullah b. Umar (Allah be pleased with them) said: Bilal and Uthman b. Talha informed me that Allah's Messenger ( صلی اللہ علیہ وسلم ) observed prayer in the interior of the Ka'ba between the two Yemenite pillars.
