The Sikh religion was founded by Guru Nanak in the late 15th century. Sikhism had its inception in the Hindu bhakti movement that started in south India as a reaction against the caste system & Brahmin domination of ritual. It was conceived at a time of great social unrest & was an attempt to fuse the best of Islam & Hinduism. The holy text named Adi Granth Sahib was completed by 5th Sikh guru & declared by the 10th to be a guru in its own right capable of providing leadership to the community.

Sikhism doesn't believe in  Idol worship.They believe in Khalsa. There are five emblems associated with Khalsa : Kesh (a khalsa must not cut his hair) , Kangha (comb) , Kacch (drawers; worn by soldiers), Kirpan (sabre), and Kada (a steel bracelet). The Kada is said to be a charm against evil, some claim it to remind believers that they are shackled to the God.
