The names of Allah that cannot be used for humans are as follows. They are acceptable if you put Abdul ("servant of") in front of them, but without Abdul they shouldn't be used.
- ar-Rahman: "The Most Gracious", this name is considered a synonym of Allah, not just an attribute, for this reason humans shouldn't use it.
- al-Quddus: "The Holy", shouldn't be used because humans cannot claim holiness.
- al-Khaaliq and al-Khallaaq: "the Creator".
- al-Mutakkabir: "The Self-Glorifier", when used for a human it means "arrogant", which is not a good meaning.
- al-Awwal: "The First", synonym of the Christian "Alpha", shouldn't be used because it refers specifically to God.
- al-Aakhir: "The Last", synonym of the Christian "Omega", shouldn't be used because it refers to God only.
- al-Baatin: "The Hidden One", shouldn't be used because it refers to God and cannot refer to a human.
- al-Hakam: "The Judge"
- al-Ahad: "The One"
- as-Samad: "The Eternal, the Uncaused Cause of All Being"
- ar-Razaaqi: "The Giver of Provision"
- al-Jabbaar: "The Subduer"
