DHÂKIR - ذاكر
Literally and Etymologically: The one who remembers, invokes, or brings to mind. Like the word dhikr, it derives from the root dh-k-r (ذ ك ر ), which signifies remembrance and recollection, which are the opposites of ghaflah. It refers to one who narrates, recites, or proclaims from memory.
As an Islamic Term: The person who performs dhikr; one who consciously and consistently recites the names, attributes and praises of Allah (‘Azza wa jalla). A dhâkir is not merely one who offers verbal du'â and dhikr, but an awakened rûh who glorifies his Khâliq both verbally (lisan-ı kâl) and through the language of his being (lisan-ı hâl), thereby transforming his entire existence into a mirror of continuous remembrance since all verbal dhikr and du'â are the manifestation of inner feelings and thoughts in the form of words or actions.

Yes, look to the ma’nawî collective personality of that absolute proof: The face of the earth is a masjid, Makkah a mihrab1 and Madinah a minbar2. Our Prophet ‘Alayhissalâtu Wassalâm, who is the evident proof, is the Imam to all the people of îmân, the preacher to all mankind, the leader of all the prophets, the sayyid of all the awliyâ and the chief leader of the circle of the dhikr formed from all the prophets and awliyâ. He is such a luminous tree, whose living roots are all the prophets and whose fresh fruits are all the awliyâ, that all the prophets — relying on their miracles — and all the awliyâ — relying on their karâmât — confirm and sign each of his (asm) claims.
For, he says and claims
لاَ اِلهَ اِلاَّ اللّٰهُ
All those on the left and the right — that is to say, those luminous dhâkirs lined up in the past and the future — by repeating the same word through consensus (ijmâ’), in a ma’nawî manner, declare
صدقتَ و بالحق نطقت3
