17. Why did the Prophet Muhammad destroy the idols in Makkah?
Every religion has an institutional place of worship. The Kabah was built by the Prophet Abraham for the worship of One God (monotheism). Neither Abraham nor his followers ever placed an idol inside the Kabah. In later times, since it was open for all, some visitors placed idols inside the Kabah, thereby causing intrusion or unauthorized trespassing.
When the whole of Makkah came within the fold of Islam, the presence of these idols became irrelevant and therefore they were removed. This was not done as a mark of disrespect. Had there still been worshippers of these idols, they would not have been destroyed but simply relocated to their rightful temples.
