God is described in chapter 112 of the Qur'an as:[24] "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-Rahmān, meaning "The Compassionate" and Al-Rahīm, meaning "The Merciful" (See Names of God in Islam).[25]
Muslims believe that creation of everything in the universe is brought into being by God’s sheer command “‘Be’ and so it is.”[26][27] and that the purpose of existence is to love and serve God.[2][28] He is viewed as a personal God who responds whenever a person in need or distress calls Him.[26][29] There are no intermediaries, such as clergy, to contact God who states “We are nearer to him than (his) jugular vein”[30]
Allāh is the term with no plural or gender used by Muslims and Arabic-speaking Christians and Jews meaning the one God, while ʾilāh (Arabic: إله) is the term used for a deity or a god in general.[31] Other non-Arab Muslims might use different names as much as Allah, for instance "Tanrı" in Turkish or "Khodā" in Persian.
