You mean by black box the building of Kaaba in Makkah (or Mecca) in Saudi Arabia. This building is the first God house on earth and was built long time ago before Jesus (peace be upon him). In the era of Prophet Abraham and Prophet Ismael (peace be upon them), they both raised the foundation of this house that was covered. This means that it was built even before prophet Abraham. What is inside Kaaba is a usual space surrounded by four walls and ceiling. The walls are having some hangings.
The Hegira, or the migration of Prophet Muhammad from Mecca to Medina in 622 CE, was significant as it marked the beginning of the Islamic lunar calendar and the establishment of the first Islamic community. This event also allowed Islam to flourish, as Muhammad gained political and military support in Medina, which paved the way for the expansion of Islam.
