Allah is the Arabic word Muslims use for God. In Islam, Allah is the one creator, sustainer, judge, and merciful Lord of all existence. Muslims do not understand Allah as a tribal deity or as one god among many.
What the word Allah means
The Arabic word is used in the Qur’an for the one God. Arabic-speaking Christians also use Allah for God in Christian worship and Arabic Bibles, showing that the word itself is not uniquely a label for a separate Muslim deity.
Islamic theology nevertheless describes God in distinctly Islamic ways, especially through strict monotheism, prophecy, and the Qur’an.
Is Allah the God of Abraham?
Muslims understand themselves as worshiping the God of Abraham, Moses, Jesus, and Muhammad. The Qur’an repeatedly places Islam within a history of earlier monotheistic revelation.
Christians and Jews do not accept all Islamic claims about revelation or Muhammad, so overlapping Abrahamic language does not erase serious theological disagreement.
Allah in relation to the Bible
The English Bible normally uses the word God, not Allah, because English follows its own vocabulary. Arabic Bible translations use Allah where English translations use God.
The Qur’an speaks about many biblical figures, but it is a separate scripture with its own narratives, emphases, and theology.
The oneness of God
Islamic belief in tawḥīd insists that God has no partner or equal. The Qur’an rejects worship of created beings and denies that God is one member of a divine family.
This is a major point of disagreement with mainstream Christian Trinitarian doctrine, which Christians understand as one God in three persons rather than three gods.
Short answer
Allah means God in Arabic, and Muslims worship Allah as the one God of Abrahamic monotheism. Shared reference to God does not mean Islam, Christianity, and Judaism have identical theology.
