What is the ruling on naming the Holy Quran as "Al-Qur'an" (with the hamza replaced by an 'ayn), as some elderly people do in Algeria, despite their ability to pronounce the hamza?

The linguistic substitution of the glottal stop (hamzah) with the sound /ayn/ (al-ananah) is an ancient Arabic dialect attributed to the tribe of Tamim. They replace the hamzah with an /ayn/, for example, saying "anta" instead of "anta" (you), and "annaka" instead of "annaka" (that you). The reason for this substitution is the proximity of the articulatory points of the two letters. This was found in the language of Quraysh, Tamim, Qays, Asad, and those who lived near them. It is permissible to use this dialect, especially for the elderly who find it difficult to change their accustomed pronunciation. However, it is preferable to adhere to the original pronunciation to avoid ambiguity and confusion for the listener.
