Someone sets up a stone idol, and all the world worships it as the Lord. Those who hold to this belief will be drowned in the river of darkness. And this is in the Guru Granth Sahib. This notion of being against idol worship comes out very clear in this quotation, and that is another idea that is often associated with Islam. But as I mentioned, there's also many parallels with Hinduism. In the first video on Sikhism, I give you this quote from Guru Nanak. The world is a drama staged in a dream, which alludes to the Hindu notion of maya.
