Bismillah, alhamdolillah
yes I can do it.
First of all, if we go back, early arabs, like Aad and Thamoud where polytheists, but this changed into monotheist due to their prophets. And after this I don't know.
Later on Ibrahim(Abraham) went to Mecca and there he settled Ismail and Hajar and went back to Sarah. Ismail and Hajar lived among the arabs, and Ismail learned arab language from them and he spoke it fluently and married among them women. So he was (let's say) one of them.
Ismail was a messenger and prophet. When he grew and became older he invited them to accept monotheism and the arabs responded positive and Makkah was the centre of religion and also the centre(leader) of the arab world. He(Abraham) would come to Makkah once per year to perform the rites of Hajj with his family until he died. His son Ismaa'eel who had by then married a woman from the tribe of Jurhum, continued the tradition of Hajj and looked after the Ka'bah until he died(the autenticity of this sentence is doubtfull). So the arabs were all muslims and following the religion of Ibrahim, alhamdolillah.
Then a long time passed by and amr ib luhay was the first one to introduce shirk(polytheism). Idolatry was introduced into Arabia by 'Amr ibn Luhay. The story is that one day he went on a trip to Syria (or Iraq?), and there he saw people worshipping idols and he thought that there was nothing wrong with this act and he even liked it. So he brought an idol with him back to Makkah. Bringing the idol to Mecca, where he erected it in the courtyard of Kaaba, and invited people to worship it. This act was the beginning of idolatry in the peninsula; it quickly spread and became the dominant belief of the people in the region. The number of idols brought to the Kaaba increased day by day, until there were finally a great number; every tribe, every family even, had their own idols. It is known that the number of idols in the Kaaba reached 360 just before the advent of Islam. The most famous of these idols in the Hejaz were Hubal, Isaf, Naila, Wadd and the three goddesses Lat, Manah and Ozza, who were known as “Allah’s daughters”. Hubal was the first idol brought to the Kaaba and it was the most respected idol. Hubal was made of red agate and had a human form. It was accepted as a god by all the Arabian tribes.
Later on there was Judaism, Christianity(not the one we know today, but monotheism-christianity) and even sorcery and many strange beliefs among them. So when the time began to pass by and the monotheism began to dissapear, some wanted to go back to the religion of Ibrahim, the monotheism instead of worshipping idols that can do nothing. But they were confused and had no clue how this religion is performed and what it commanded or forbade. So they stuck to what they were sure of and that is the belief in only one god and that is Allah and rejecting the worship of something besides him. But although the Arabs in the Age of Ignorance basically worshipped idols, they also accepted the existence of a superior God called “Allah”, who they saw as the creator. As a matter of fact, there were people who adopted Hanafiyyah, the religion of Abraham in the region; this fact is seen as evidence that monotheism was not an unknown concept in the Arabian Peninsula at the time. It is interesting that this belief, which was known to have existed in the years after the birth of Jesus, particularly in southern Arabia, and which probably came to Mecca via trade activities, found a place also in the poems of the Age of Ignorance. It is particularly interesting that the word “rahman”, used in the poetry of the Age of Ignorance to define Allah, had no plural form and was considered to denote a single God.
As stated in the Holy Quran (Al-Zumar, 39/13), the polytheist Arabs worshipped idols so that they could come closer to Allah. They knew that Allah, who waters the earth, causes the crops to grow, and provides the flocks commanded by humans, is “the Creator of all things”, “the Lord of the earth”, “Owner of the heavens and the earth”. They would pray to Allah in tumultuous times and swear grave oaths in the His name. They even allocated some portion of their crops to Allah. They prayed to Him in dangerous situations, but they forgot Him when situation passed. They sacrificed animals in the name of idols, but they also worshipped Allah. All these examples show that the Arabs’ faith in Allah was very ambiguous and there was a conflict in faith. Although the idols were seen as mediators on a conscious level, they were concerned in all parts of daily life and were the dominant objects of worship.
i am tired now, i have more info. but i think this should be enough
