The four corners of the Kâ’ba are called the four rukns. The one pointing to Damascus is termed Rukn-i-Shâmî, the one pointing to Baghdad is termed Rukn-i Irâqî, the one toward the Yemen is termed Rukn-i Yemânî, and the fourth corner is termed Rukn-i Hajer-il-aswad.
There is a Gold Gutter on the north wall of the Kâ’ba. The space between this gutter and the curved small wall, which is below the gutter and in line with it, is called the Hatîm. While making the tawâf it is necessary to make the turns outside of this Hatîm wall.
