What did Prophet Muhammad (saw) do when he entered the Ka'ba?
 Narrated Mujahid:                     Someone came to Ibn `Umar and said, "Here is Allah's Apostle entering the Ka`ba." Ibn `Umar said, "I went there but the Prophet had come out of the Ka`ba and I found Bilal standing between its two doors. I asked Bilal, 'Did the Prophet pray in the Ka`ba?' Bilal replied, 'Yes, he prayed two rak`at between the two pillars which are to your left on entering the Ka`ba. Then Allah's Apostle came out and offered a two-rak`at prayer facing the Ka`ba.' "
