The word has two major uses in the Quran. As a religious term, it is one of the Islamic names of God, and as a result features in the Muslim names such as Abdur Raqib, meaning "servant/ slave of the Watcher/ Overseer/ Ever-Watchful/ Observer".

In Urdu language, the word Raqeeb is also used for a person who is your Rival in Love. Who loves the same person you do or your Lover loves him. It is widely used in Urdu prose and poetry.

As a military term, overseer designates a military rank, conventionally considered equivalent to sergeant in other countries, and has variations such as "first overseer" etc.

In Arab armies, raqīb overseer ranks are superior to the rank of arīf (عريف), which means "expert" and is equivalent to corporal in many other countries. Raqīb ranks are immediately below the ranks of "assistant" (مساعد) and "first assistant", which are equivalent to Commonwealth ranks of warrant officer.
