Is it permissible to supplicate using the pronoun "He" (Huwa), intending Allah Almighty by it, considering it one of Allah's Most Beautiful Names, and that true absence is for Him alone?

The names of Allah are Tawqifiyyah (restricted to what has been revealed), and there is no evidence that the pronoun of the third person singular, "Huwa" (He), is one of Allah's Beautiful Names. Therefore, it is not permissible to supplicate with it. Whoever claimed that the dhikr of the elite is "the singular name" or "the hidden name" has erred, for this is not a complete statement nor a meaningful sentence. None of the predecessors mentioned it, nor does it provide the heart with knowledge or a beneficial spiritual state. Dhikr using the singular hidden name is an innovation and closer to the deception of Satan.
