Allah (English pronunciation: /ˈælə/ or /ˈɑːlə/; Arabic: الله Allāh, is a word for God used in the context of Islam and other monotheistic religions of Arabic-speaking communities. In Arabic, the word means simply "The God". It is used primarily by Muslims.
The term Allāh is derived from a contraction of the Arabic definite article al- "the" and ʾilāh "deity, god" to al-lāh meaning "the [sole] deity, God". Cognates of the name "Allāh" exist in other Semitic languages, including Hebrew and Aramaic.
In Islam, the name Allah is the supreme and all-comprehensive divine name, and all other divine names are believed to refer back to Allah. Allah is unique, the only Deity, creator of the universe and omnipotent. Muhammad's father's name was ʿAbd-Allāh meaning "the slave of Allāh".
According to Islamic belief, Allah is the proper name of God, and humble submission to His Will, Divine Ordinances and Commandments is the pivot of the Muslim faith. "He is the only God, creator of the universe, and the judge of humankind." "He is unique (wāḥid) and inherently one (ʾaḥad), all-merciful and omnipotent." The Qur'an declares "the reality of Allah, His inaccessible mystery, His various names, and His actions on behalf of His creatures."
In Islamic tradition, there are 99 Names of Allah (al-ʾasmāʾal-ḥusnā lit. meaning: "The best names"), each of which evoke a distinct characteristic of Allah. All these names refer to Allah, the supreme and all-comprehensive divine name. Among the 99 names of Allah, the most famous and most frequent of these names are "the Merciful" (ar-raḥmān) and "the Compassionate" (al-raḥīm).
Most Muslims use the untranslated Arabic phrase ʾinšāʾ Allāh (meaning "Allah willing") after references to future events. Muslim discursive piety encourages beginning things with the invocation of bismi-llāh (meaning "In the name of Allah"). There are certain phrases in praise of Allah that are favored by Muslims, including "Subhan-Allah" (Holiness be to Allah), "Alhamdulillah" (Praise be to Allah), lā ʾilāha ʾilla-llāh (There is no deity but Allah) and "Allāhu Akbar" (Allah is great) as a devotional exercise of remembering Allah(zikr). In a Sufi practice known as zikr Allah (lit. remembrance of Allah), the Sufi repeats and contemplates on the name Allah or other divine names while controlling his or her breath.
