The earth spins around the sun once every year, the moon rotates around the earth once per lunar month, and planets of solar system likewise rotate around the sun, each in its own orbit. Law of revolution also applies to atoms where electrons move around it in an orbit. Since all matter in the universe consists of atoms, this means the law of revolution applies to everything. This shows that revolution is a cosmic law. With a believer’s contemplation upon these facts, another picture of the revolution brings to one’s mind: the pilgrim’s circumambulation of the Kaaba, which is a fundamental custom of Hajj in Islam. Circumambulating around Kaabah is a symbolic act of worship which signifies submission to Allah the Almighty alone. Allah ﷻ states in the Quran: "And (remember) when We showed Ibrahim the site of the (Sacred) House (the Kaaba at Makkah), saying: Ascribe not anything (in worship) with Me, and sanctify My House fo those who circumambulate it, and those who stand up (for prayer), and those who bow (submit themselves with humility and obedience to Allah), and make prostration (in prayer), And proclaim to mankind the Hajj (pilgrimage). They will come to you on foot and on every lean camel, they will come forim every deep and distant (wide) mountain highway (to perform Hajj), "(Al-Hajj, 22:26-27).

Tawaaf

Circumambulating around Kaabah is known as Tawaaf. It is the utmost degree of love which shows that the believer wishes to sacrifice himself for the beloved Allah ﷻ. This demonstrates that believer wishes to prove that he desires nothing but Allah ﷻ.
