God
Main article: God in Islam
Allāh is the term with no plural or gender used by Muslims to refer to the one God, while ʾilāh is the term used for a deity or a god in general.[26] Other non-Arab Muslims might use different names as much as Allah, for instance "Tanrı" in Turkish or "Khodā" in Persian.Islam's fundamental concept is a rigorous monotheism, called tawhīd. God is described in chapter 112 of the Qur'an as:[27] "Say: He is God, the One and Only; God, the Eternal, Absolute; He begetteth not, nor is He begotten; And there is none like unto Him." (112:1-4) Muslims repudiate the Christian doctrine of the Trinity and divinity of Jesus, comparing it to polytheism but accept Jesus as a prophet. In Islam, God is beyond all comprehension and Muslims are not expected to visualize God. God is described and referred to by certain names or attributes, the most common being al-rahman, meaning "the compassionate" and al-rahim, meaning "the merciful" (See Names of God in Islam).[28]
Muslims believe that the purpose of existence is to worship God.[29] He is viewed as a personal God who states “We are nearer to him than (his) jugular vein”[30] and responds whenever a person in need or distress calls Him.[7][31] There are no intermediaries, such as clergy, between God and the creation that he brought into being by the sheer command “‘Be’ and it is.”[7][32]
