The historical record suggests that Mecca was settled around the 4th century A.D. by the Yemeni tribe of Khuzaa'h, joined later by Mohammed’s tribe the Quraish. The Kaaba was built around the early 5th century likely by Asa'd Abu Karb, for Arabian Star Family worship after the black stone made it's way to Mecca, most likely from Yemen. Early reporters recounted that prior to the construction of the Kaabah, a tent occupied the site. The Kaaba eventually housed 360 idols dedicated to Arabian moon, sun, star and jinn (demon) worship. It is no secret that the black stone that Muslims still prostrate themselves toward 5 times a day, venerate, and circumambulate, is the same black stone idol that pagan Arabians venerated and circumambulated. In other words, the Quraish established the rituals that Mohammed eventually adopted and then adapted to his religion.
Since no prophet came to children of Ishmael in 3,500 years
the Arabs gradually became pagans and started worshiping
angels and pious people as being close to God. Then Allah
had mercy on Arabs and sent His last prophet Muhammad.
An idol called ‘Manat’, for instance, was worshipped in a place known as Al-Mushallal near Qadid on the Red Sea. Another, ‘Al-Lat’ in Ta’if, a third, ‘Al-‘Uzza’ in the valley of Nakhlah, and so on and so forth. Polytheism prevailed and the number of idols increased everywhere in Hijaz. It was even mentioned that ‘Amr bin Luhai, with the help of a jinn companion who told him that the idols of Noah’s folk – Wadd, Suwa‘, Yaguth, Ya‘uk and Nasr – were buried in Jeddah, dug them out and took them to Tihama. Upon pilgrimage time, the idols were distributed among the tribes to take back home. [Bukhari 1/222] Every tribe, and house, had their own idols, and the Sacred House was also overcrowded with them. On the Prophet’s conquest of Makkah, 360 idols were found around Al-Ka‘bah. He broke them down and had them removed and burned up. [Mukhtasar Seerat-ar-Rasool p.13-54]
Polytheism and worship of idols became the most prominent feature of the religion of pre-Islam Arabs despite alleged profession of Abraham’s religion.
Traditions and ceremonies of the worship of their idols had been mostly created by ‘Amr bin Luhai, and were deemed as good innovations rather than deviations from Abraham’s religion. Some features of their worship of idols were:
Self-devotion to the idols, seeking refuge with them, acclamation of their names, calling for their help in hardship, and supplication to them for fulfillment of wishes, hopefully that the idols (i.e., heathen gods) would mediate with Allâh for the fulfillment of people’s wishes.
Performing pilgrimage to the idols, circumrotation round them, self-abasement and even prostrating themselves before them.
Seeking favour of idols through various kinds of sacrifices and immolations, which is mentioned in the Qur’ânic verses:
"And that which is sacrificed (slaughtered) on An-Nusub (stone-altars)" [Al-Qur'an 5:3]
