What is the meaning of "the Hand of Allah" in Arabic, in a way that does not delegate the meaning, and the meaning is known as you claim?

It is impermissible to dispute about Allah's attributes. One must believe in the attributes Allah has affirmed for Himself in a manner befitting Him, without any resemblance to created beings. The argument of anyone who claims that the word "hand" is ambiguous and could mean power, favor, or a physical hand, and that the obligation is to relegate its meaning (tafwid), is erroneous and refuted by the texts. Affirming the attribute of two hands for Allah Almighty, in a manner befitting Him, is the belief of Ahlus-Sunnah. The word "hand" has appeared in the Qur'an in three forms: singular, dual, and plural, and each form has its specific connotation. Thus, His saying, the Almighty: "I created with My own two hands" differs from "which Our hands have wrought," because the former indicates direct action. Prophetic narrations affirm that Allah created Adam with His hand, planted the Paradise of Firdaws with His hand, and wrote the Torah with His hand. This establishes a virtue and distinction for Adam; had "hand" meant power, there would have been no such distinction. Allah Almighty has two hands, as He has affirmed for Himself, so we affirm them for Him while believing in His transcendence above resemblance to created beings, and human intellects are incapable of comprehending the essence of His attributes.
