Diffusion of culture and religion over millenia is complicated. Grand condemnations based on personal experiences don't do the subject justice . The article was fresh for me.
The Original Black African Arabs of Arabia Part 4 (The Black Stone, The Black Tribe of Koreysh, The Black Prophet By Ogu Eji Ofo Anu
The Black Stone, the Black Tribe of Koreysh, the Black Prophet
The Kaaba - the Black Stone
The Kaaba was a pagan shrine of great antiquity which housed the black stone, a meteorite that was probably brought by the Kushitic Black Arabs from Kushitic Ethiopia where such worship was routine. Pagan rites were routinely performed at the Kaaba in Mecca.
Richard King stated in his book, “Melanin: A Key to freedom” on the issue of the Kaaba stone:
“… for many followers of Islam the experience of viewing the Black Stone Meteorite El Ka’aba in Mecca evokes the inner vision image and experience of God. This inner vision event was likely to have been experienced by the same Africans who brought the Black Stone from Ethiopia to Arabia long before the birth of the Prophet Mohamet. It is equally important to note that in Kemet, the genetic child of Ethiopia, Black Stones were given Divine Value. Black stones were often placed as the all Black pyramiadon cap stones upon the top of pyramids, an all black stone room (rose granite being a black granite with flecks of red as the King’s chamber is the highest room in the interior of the Great Pyramid of Giza), and a special system of linear measurement being used by Kamites when working in Black Stone, the Black Cubit or nilometric cubit.”
Although some Muslim hadiths assert that Abraham the ancestor of the Adnaniyun tribe of the Arabs, had built up the Kaaba with the help of his son Ismail/Ishmael upon the instruction of Allah, more academically inclined historians generally accepted that at the time Mohammed began his preaching, there was no recollection of any Abraham nor Adnaniyun, nor Ismail who had purportedly built the Kaaba. There was instead a living tradition of a matriarchal goddess worship and rites dating back to ancestral Ethiopia Kush where matriarchal goddesses have been worship in its most developed form since the beginning of time.
The city of Mecca was considered a holy place and the destination of pilgrims long before the prophet Muhammad. Kushitic Black Arabs and other Arabized tribes would bring yearly offerings to the Kaaba, or, make pilgrimages as part of a pattern of Kushitic religious rites which venerated the matriarchal deity of Mecca - Alaat.
Mohammed’s new religion which had emphasized the mythological masculine ancestor Abraham together with his Hebrew male proto-God was antithetical to all the known traditions of Mecca. The basic issue between Mohammed and his Koreysh persecutors who drove him out of Mecca was that he had preached an alien and foreign philosophy which they could not understand nor tolerate. Most of Mohammed’s own tribe-the Koreysh- the keepers of the Kaaba- officiated over the worship of the Kushitic originated Godess Alaat.
