The Background of Idol Worshipping
Namrud ibn Kanan bin Kush was an idol worshipping king who was the most atrocious and oppressive idol worshipper and the first idol worshipper from the Tahmores dynasty. He would carve the faces of those who would pass away in wood and worship their statue.
In the book Tabaqhat Nasiri we read: Namrud ibn Kanan bin Kush ibn Ham bin Nun, was the first to commit tyranny after the storm (of Nuh) and wore a crown. He was the one who occupied the land of Babylon, differentiated between Arabs and non-Arabs, built an establishment for worshipping idols, worshipped idols, built idols with gold and silver, embellished them with jewelry, appointed Azar the idol maker as his treasurer and idol keeper, followed astrology and there is a great chance that those idols were made based on the form of the stars and were worshipped by them.
The Starting Point of Idol Worshipping in Mecca:
Imposing the great idol of Hubal from Syria upon the people of Mecca by the tyrant Amr ibn Lahiyy and forcing them to worship it:
The tribe of Jarhum in the Haram (Mecca) rebelled and this event coincided with the fall of the Sheba rule and the coming of Harithah ibn Thalabath ibn Amr ibn Amir to Mecca. They wanted to reside in the same location that the tribe of Jarhum was residing in but Jarhum resisted and a battle was triggered, but Bani Harithah, being from Khuzaah, prevailed and occupied the Kabah. Their leader at the time was Amr ibn Lahiyy who drove the rest of the people of Jarhum away from Mecca. Ibn Lahiyy was Rabiah ibn Harithah ibn Thalabat ibn Amr Maziqiya ibn Amir. In a tradition the Prophet says (A.S.):رایت عمرو بن لحی یجر قصبه یعنی احشاءه فی النار, because he was the one who broke the tradition and innovated the Buhairah, Saaibah and Hami and altered the religion of Prophet Ismail and spread idolatry.
Some historians have narrated that: Amr ibn Lahiyy once traveled from Mecca to Syria. When he arrived at the land of Balqaa and the city of Maaab, he asked the Amaliqah people, who were the children of Amlaq (or Amleeq) bin Lawidh bin Saam bin Nuh, what they were worshipping. They replied: These are idols which we request rain from at times of drought, and they send us rain and whenever we need help they come to our help! Amr ibn Lahiyy said: Can you give an idol to introduce to the people of Arabia to worship as you do? The Amaliqah gave him the idol Hubal and Amr brought the idol to Mecca and forced everybody to worship it.
Masoudi writes: and when Amr ibn Amir and his children departed from Marib, Bani Rabiah parted ways and went to Tuhamah; they were called Khuzaaah due to their separation from the rest of the clan because the verb khazaa means to separateand the Khuzaaah took custodianship of the Kabah, the first of them being custodian was Amr ibn Lahiyy and Lahiyyss name was Harithah ibn Amir. Amr changed the religion of Ibrahim and distorted it and prompted the people to worship idols. According to a report, he went to Syria and saw a group who would worship idols; they gave him an idol to install on the Kabah. The tribe of Khuzaah became powerful and Amr ibn Lahiyy was oppressing everybody. One of the monotheists from the tribe of Jarhum addressed Amr saying: Oh Amr! Do not oppress the people of Mecca because this is a sacred and holy land. Ask about the fate of the people of Aad and the Bani Amaleeq which had camels there. Ask where they ended up? This is how people are annihilated. Amr ibn Lahiyy had placed many idols around the city of Mecca and idol-worshipping spread around Mecca and the pure religion of Ibrahim was largely discarded.
In line with the above Shahnat ibn Khulf Jarhumi says: Oh Amr! You have set numerous gods around the Kabah when we would solely worship one lord. You have established a number of gods for the people; know that in the future God will choose another custodian of the Kabah to replace you. It has been said that Amr ibn Lahiyy lived for 345 years and the authority of the Kabah was with the tribe of Khuzaaah.
