Ar-Raqīb - The Ever Watchful over everything

Ar-Raqīb is the one who knows, the one who preserves, the one who watches for a given object so that it is never ignored and who observes it so closely and constantly, such a one is called a raqīb. (This word) may be said to be derived from knowledge and preservation, though (coupled) with the consideration that it is close and constant and that it is related to something that is forbidden, the approach to which is guarded.

The characteristic of watchfulness in man is praiseworthy only if his observation is directed to his Lord and his heart. That takes place when he knows that God is his watcher and observer in respect of everything, and if he recognises the fact that he himself and Satan are his enemies and that these two enemies avail themselves of every opportunity to induce him to fall victim to negligence and disobedience, as the result of which he is on his guard against these things by observing their ambushes, deceit and their starting places in order that the outlets and avenues (available to them) might be blocked off. This is his observation.
