According to Islamic belief, Allah is the most common word to represent 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 (aḥad), all-merciful and omnipotent.
In Islamic tradition, there are 99 Names of God (al-asmā’ al-ḥusná lit. meaning: ‘the best names’ or ‘the most beautiful 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 God, the most famous and most frequent of these names are “the Merciful” (al-Raḥmān) and “the Compassionate” (al-Raḥīm).
Most Muslims use the untranslated Arabic phrase in shā’ Allāh (meaning ‘if God wills’) after references to future events. Muslim discursive piety encourages beginning things with the invocation of bismillāh (meaning ‘in the name of God’).
There are certain phrases in praise of God that are favored by Muslims, including “Subḥān Allāh” (Holiness be to God), “al-ḥamdu lillāh” (Praise be to God), “lā ilāha illā Allāh” (There is no deity but God) and “Allāhu akbar” (God is greater) as a devotional exercise of remembering God (dhikr). In a Sufi practice known as dhikr Allah (lit. remembrance of God), the Sufi repeats and contemplates on the name Allah or other divine names while controlling his or her breath.
