In this summary, there is an effort to explain the concept of monotheism and oneness in Islam and Sikhism. Sikhism is the youngest of the world religions and the doctrines of a monotheistic religion founded in the Punjab area of India in the fifteenth century by Guru Nanak and combining elements of Hinduism and Islam. A Sikh believes (EK ONKAAR) there is only One God. IK ONKAAR the most significant word used in the Sikh teachings. But believe in one God in Sikhism is the same Muslim's believe? However, some believe that the first part of this statement of faith ( La ilaha illa'Llah ), expresses the absolute monotheism which is inherent in Islam “There is no god other than God." This is the essence of the Muslim profession of faith ( shahadah ) (Kristu, Jyoti). Pronouncement of the Islamic creed, the Shahadah , is the supreme religious act. Its mere recitation suffices for an entry into the "community of the believers." this is also rejection of polytheism, the destruction of idols, and the witness given to the one and unique God, the Lord and Creator of all that exists?
