Is the remembrance of God by His names, such as "Allah Allah" or "Hu Hu," using the fingers or a rosary, considered an innovation?

It has not been reported in Islamic law to mention a mere name among the names of Allah Almighty, such as (Allah) or (Ya Latif) repeatedly. Nor has this been authentically reported from the Prophet, peace be upon him, or from his companions. All good lies in following those who have preceded us. Likewise, it is not permissible to mention Allah with (Hu Hu Hu), for "Hu" (He) is not among Allah's Most Beautiful Names.
