The Moslem faith was started by the Prophet Muhammad about 1500 years ago in present day, Saudi Arabia, but I believe the Sikh faith is only about 500 years old and was originally centred around the Punjab region of India. Sikhs follow the writings of ten different Guru's.
Moslem means 'one who serves God' and Sikh means 'disciple'.
Both religions believe in one God who cannot/has not taken human form. Sikhs do not believe in fasting as Moslems do when celebrating Ramadaan. The Sikhs do not worship the many Gods of their fellow Indians who happen to be Hindu, nor do they follow the caste system of the Hindus.
Both religions believe in the importance of family life and do not celebrate celibacy in the manner of the Catholic clergy. Sikhs also believe in the full equality of women and reject the wearing of veils for women, though their menfolk wear turbans and do not cut their hair.

The Moslem faith is the fastest growing faith in the world and the second largest religion in GB after Christianity. Hindus are more prevalent in the UK than Sikhs, who form quite a small, but nonetheless very important world religion.
