the act of going round the kabah seven times during hajj teaches
Tawaf (Arabic: طواف ‎, Ṭawāf; literally going about) is one of the Islamic rituals of pilgrimage. During the Hajj and Umrah, Muslims are to go around the Kaaba (the most sacred site in Islam) seven times, in a counterclockwise direction; the first three circuits at a hurried pace on the outer part of the crowd, followed by four times closer to the Kaaba at a leisurely pace. The circling is believed to demonstrate the unity of the believers in the worship of the One God, as they move in harmony together around the Kaaba, while supplicating to God.
