This is the first in a series of articles contrasting Allah and Yahweh.
Muslims and Christians agree there is one God but disagree as to His name, nature, and attributes.
The god of Islam is Allah, meaning “the god” in Arabic. In the days of Islam’s founder, Muhammad, this meant that of all the tribal gods worshiped on the Arabian Peninsula, Allah was the only true deity.
Key to the Islamic concept of God is the doctrine of tawhid, or absolute oneness. It’s more than strict monotheism. Tawhid celebrates Allah as singular, indivisible, and monolithic.
Muslims insist that Allah has no “partners.” To ascribe partners to Allah — for example, to say that Jesus is the Son of God, or that God exists as a Trinity — is to commit the unpardonable sin of shirk, which damns a soul to hell.
The Qur’an makes it clear that Allah stands apart from his creation and does not engage in personal relationships. For example, Surah 17:111 reads: “Praise be to Allah, who begets no son, and has no partner in (His) dominion …”
In addition, the Qur’an instructs its readers to reject any notion that God exists as more than one person. It wrongly implies that Christians worship a Trinity consisting of God, Jesus, and Mary (Surah 4:171; 5:73, 116).
Further, Islam understands these to be three separate gods, and the Qur’an strongly warns Muslims against worshiping anyone but Allah. Here, Muslims and Christians may find some common ground, for Christians both reject the notion of Mary as a god, as well as the idea that three separate gods make up the Trinity.
In No God But One, Nabeel Qureshi points out that the Qur’an clearly denounces polytheism but does not exclude the possibility of Allah existing in tri-unity. Put another way, Qureshi says the Qur’an does not explicitly say Allah cannot exist as one God in three persons, even though Muslims strongly reject the biblical doctrine of the Trinity.
