What is the wisdom behind performing the rituals of Hajj in this manner?

The Kaaba is built of stones, and it was built by Abraham and Ishmael (peace be upon them). Abraham was building and Ishmael was handing him the stones, while they both said: "Our Lord, accept from us; indeed, You are the All-Hearing, the All-Knowing." And Hajj has great benefits, among them: establishing the remembrance of Allah, the forgiveness of sins, and worldly and otherworldly benefits. A Muslim must submit to Allah's command regarding the rituals of Hajj, as it is an act of worship purely for Allah. The human intellect's inability to fully grasp the complete wisdom behind it increases one's faith and submission to Allah.
