Sikhism considers idol worship a false practice and is prohibited.Idolatry or idol worship, also referred to as But-prasati or Pahan Pooja or Murti Pooja, is the worship of any physical object such as statues, images, or sculptures of any deity, human or being with divine attributes.
During the era of the Sikh gurus and bhagats, in Hinduism, a murti (Devanagari: मूर्ति), or murthi, or vigraha or pratima was worshiped, rituals were performed, and Sikhs believed that spiritual wisdom was lacking in Indian society. This was believed to have been a manipulation by the priestly caste to keep the power in their hands. Sikh gurus and bhagats spoke out against this practice and informed people about the perceived spiritual disadvantages of idol worship.
In letter to Aurangzeb called Zafarnamah, Guru Gobind Singh called himself an "idol breaker" (But-Shikan - ਬੁਤਸ਼ਿਕਨ).
In many compositions Guru Gobind Singh called Idol worshipper a Foolish, Lowest intellect as Animals. In 33 Savaiyey, Guru Gobind Singh states in Line 19 and 20: You will not get a place, even very small one in the abode of the Lord; therefore O foolish creature ! you away become careful even now, because by wearing a garb only, you will not be able to realise that Accountless Lord. Why do you worship stones ?, because the Lord-God is not within those stones; you may only worship Him, whose adoration destroys clusters of sins;
As per narration of Dabestan-e Mazaheb, Bhai Bhairo, a Sikh, smote the nose of an idol of Hindu goddess at Naina Devi near Anandpur Sahib. Hindu kings made a complaint to Guru Gobind Singh, who asked Bhairo to clarify his position. Bhairo denied that he had removed the nose from the idol and in turn asked the idol to become witness. When the complainant kings argued that the goddess cannot speak, Bhairo replied that if the goddess (idol) cannot speak and protect her own body then what good you expect from her?
