Is it permissible to change the name "Abd Al-Rahman" because its bearer does not know the alphabet, or is that not permissible?

Naming a child "Abd al-Rahman" is among the most beloved names to Allah Almighty, and it should not be changed, as it cannot have a negative impact. It is recommended to supplicate frequently for the son, especially the supplication of a parent for their child, and to be diligent in supplicating during times of response, by seeking assistance through prayer, the Greatest Name (al-Ism al-A'ẓam), and the supplication of Yunus (peace be upon him), while also utilizing explanatory methods and educational approaches in teaching him.
