What is meant by saying that "they will not return"?

Imām Ibn al-Jawzī (d. 597 AH / 1201 CE) summarized the scholars' opinions in his book "Zād al-Masīr" as follows:

1. They will not return from their misguidance. [Qatādah and Muqātil]
2. They will not return to Islām. [Al-Suddī]
3. They will not return from their deafness, muteness, and blindness. The act of "returning" was attributed to them because they turned away by their own choice, due to the dominance of their desires over seeking guidance through the means available to them. They were not actually deaf or dumb, but because they turned away from hearing the truth and espousing it, they were like the deaf and mute.
