What is the ruling on producing audiobooks for scholars like Ibn al-Qayyim, Ibn Taymiyyah, and Ibn Kathir, in order to help those who do not find time to read their books?

This work is very beneficial, especially with the correctness and quality of the reading. However, the questioner should first search for the read books already available on the internet so as not to duplicate their recording, as there may be existing charitable projects specifically aimed at the visually impaired.
