The Kaaba is built around a sacred black stone, a meteorite that Muslims believe was placed by Abraham and Ishmael in a corner of the Kaaba, a symbol of God's covenant with Abraham and Ishmael and, by extension, with the Muslim community itself.
Beetles of the Scarabaeidae family (dung beetle) roll dung into a ball as food and as a brood chamber in which to lay eggs that are later transformed into larvae. For these reasons the scarab was seen as a symbol of this heavenly cycle and of the idea of rebirth or regeneration.The Egyptian god Khepri, Ra as the rising sun, was often depicted as a scarab beetle or as a scarab beetle-headed man.The ancient Egyptians believed that Khepri renewed the sun every day before rolling it above the horizon, then carried it through the other world after sunset, only to renew it, again, the next day.or reasons that are not clear (although no doubt connected to the religious significance of the Egyptian god Khepri), amulets in the form of scarab beetles had become enormously popular in Ancient Egypt by the early Middle Kingdom (approx. 2000 BCE) and remained popular for the rest of the pharaonic period and beyond.
