It is narrated from Hazrat Ibn Umar (may Allah be pleased with them) that I asked Hazrat Bilal (may Allah be pleased with him) where the Holy Prophet (peace and blessings of Allah be upon him) prayed when he entered the Ka'bah. He replied: Between two pillars (and at that time there was a distance of three cubits between the Holy Prophet (peace and blessings of Allah be upon him) and the wall).
