Does your statement in Fatwa no. 167179, that "the meanings of Arabic letters and words are the same as the meanings of the Qur'an," imply that the meanings subsisting in Allah are identical to the meanings subsisting in creation, despite the Salaf's belief that what subsists in Allah does not subsist in anyone else?

The words of Allah, in their letters and meanings, do not resemble the words of created beings. Just as Allah's attributes do not resemble the attributes of created beings, so too His words do not resemble their words, nor do their meanings resemble His meanings, nor do their letters resemble His letters. The Qur'an was revealed in the Arabic language, so its letters and words are Arabic in both لفظ (pronunciation/wording) and معنى (meaning).
