What is the ruling on naming a newborn "ʿAbd al-Raḥmān" as an optimistic hope that he will be such, and not as a commendation?

Naming a child "Aabid-ur-Rahman" (Worshipper of the Most Merciful) is beloved in Islamic law because it signifies servitude to Allah Almighty, and there is no difference between it and "Abd-ur-Rahman" (Servant of the Most Merciful). The name "Aabid-Allah" (Worshipper of Allah) was mentioned among the Companions, such as Aabid-Allah ibn Sa'd al-Muharibi, who came to the Prophet, peace and blessings be upon him.
