Q: What reply should be given to Hindus when they they ask me that idol worshipping is haram, why do Muslims bow down in front of the ka’ba? It is also a stone thing like and idol.
A: When the Hindus are not prepared to accept the principles of Islam then their statements pertaining to the secondary things of Islam are of no significance. The Ka`bah is just the direction of prayer, whether the building is existent or not Muslims all over will face in the same direction. The same does not apply to idols and idolaters.
And Allah Ta’ala (الله تعالى) knows best.
