Sir Richard Francis Burton,
Personal Narrative of a Pilgrimage to Al-Madinah & Meccah…
“ The Kuraysh tribe, who rebuilt the house, failing in funds of pure money, curtailed its proportions by nearly seven cubits and called the omitted portion Al-Hatim. In digging the foundation they came to a green stone, like a camels hunch, which, struck with a pickaxe, sent forth blinding lightning, and prevented further excavation. The Kuraysh, amongst other alterations, raised the walls [p.323] from nine to eighteen cubits, built a staircase in the northern breadth, closed the western door and placed the eastern entrance above the ground, to prevent men entering without their leave. ”
