Al Raqib – The Watchful

He who observes all creatures, and every action is under His control.

“Thou knowest what is in my heart, though I know not what is in Thine. For Thou knowest in full all that is hidden. “Never said I to them aught except what Thou didst command me to say, to wit, ‘Worship Allah, my Lord and your Lord’; and I was a witness over them whilst I dwelt amongst them; when thou didst take me up thou wast THE WATCHER OVER THEM, and Thou art a witness to all things. “If Thou dost punish them, they are Thy servants: if Thou dost forgive them, Thou art the Exalted in power, the Wise.”
(5:116…118) The Holy Quran

Al-Raqeeb, that is, the One Who truly ever watches over us, is, of course, Allah.
