Why do we circumambulate 7 rounds of Kaaba ?

The act of circumambulating the Kaaba seven times during the Hajj pilgrimage or Umrah holds deep symbolic and spiritual significance in Islam.
Spiritual purification and submission: It symbolizes the unity and submission of the believers to Allah. Circumambulating the Kaaba signifies being in complete submission to the will of God, as pilgrims follow the prescribed rituals of Hajj or Umrah.
Following the footsteps of Prophet Muhammad: Tradition holds that Prophet Muhammad circumambulated the Kaaba seven times during the Farewell Pilgrimage, setting the precedent for this act.
Unity and completion: The number seven holds significance in many cultures and religions, often symbolizing completion or perfection. By completing seven circuits, pilgrims seek to complete their spiritual journey and express their unity with God and fellow believers.
Symbolism of the seven heavens: Some interpretations link the seven circuits to the seven heavens in Islamic belief, representing a spiritual journey towards closeness to Allah.
Honoring Ibrahim and Hajar: The circumambulation also commemorates the actions of Prophet Ibrahim (Abraham) and his wife Hajar, who walked around the hills of Safa and Marwa seven times in search of water, a ritual replicated during Hajj and Umrah.
Ultimately, the act of circumambulating the Kaaba seven times encompasses spiritual devotion, submission, unity, and completion of the rituals, embodying the essence of the pilgrimage experience in Islam.
