Sikhs believe that God has been given many names, but they all refer to the One God, VāhiGurū. Sikh holy scripture (Guru Granth Sahib) speaks to all faiths and Sikhs believe that members of other religions such as Islam, Hinduism and Christianity all worship the same God, and the names Allah, Rahim, Karim, Hari, Raam and Paarbrahm are, therefore, frequently mentioned in the Sikh holy scripture (Guru Granth Sahib) . God in Sikhism is most commonly referred to as Akal Purakh (which means "the true immortal") or Waheguru, the Primal Being.
