There is scholarly caution around using names like Rahman, Aziz, or Kareem alone (especially with the definite article ‘Al-‘, as in Ar-Rahman or Al-Aziz) as a standalone human name, since these can be among Allah’s exclusive attributes and using them unmodified for a person may imply sharing in His unique qualities. The safer and traditionally recommended practice is to always pair such names with ‘Abd’ (servant) — Abdur-Rahman, Abdul-Aziz, Abdul-Kareem — which preserves the beautiful meaning while correctly expressing servitude rather than equivalence. Some scholars permit certain names like Rahim or Kareem alone when clearly understood in a human, non-absolute sense (e.g., ‘a kind/generous person’), but attaching ‘Abd’ remains the widely recommended and safest approach.
