The Black Stone i.e. Hajar-e-Aswad is the most sacred of all the stones preset on Earth or even in the universe. Inside of Masjid-al-Haram in Makkah, Saida Arabia; Hajar-e-Aswad remains fixed to the southeast wall of the holy Kaabah in an enclosed silver casing

History of Black Stone is very interesting and it has been thought as a meteorite by most of the people. But Muslims believe that it was taken from Jannah at the time when Hazrat Adam and Amma Hawa were looking for a place to worship Allah.
