Nowadays, many people wonder: “Why do Muslims perform Hajj?”
The counterclockwise circumambulation around the Ka`bah resembles the movement of everything in this universe from the smallest to the biggest thing. It indicates the movement of the universe. The whole universe from the atom to the galaxy rotates in a direction.
Rotation is such a universal phenomenon which includes everything. The electron revolves around the nucleus, the moons orbit their planets, the planets orbit their suns, the stars orbit their galaxies, and energy rotates in its path. All rotate in one direction exactly like the way Muslim pilgrims circumambulate the Ka`bah. Circumambulation is a symbol of the nature of the universe which Allah has created in this universe.
