Idolatry is when people worship statues or pictures as if the statue or picture is a god. In Sikhism, they don't believe in idolatry. Instead, Sikhs believe in one god who is everywhere and in everything. They believe in worshiping god through prayer and living a good life, instead of through statues or pictures. Sikhs also believe in the importance of respecting and honoring their holy book, the Guru Granth Sahib, which contains teachings and songs of the Sikh gurus and other spiritual leaders. So, idolatry is not allowed in Sikhism, because it goes against their belief in one god and honoring their holy book.
