Is it permissible to work as an accountant for Israelis, recording their donations to their religious and charitable institutions? And is that considered assisting them? And what should one do if they cannot find any other work?

It is permissible to deal with non-Muslims in accounting work that is Islamically permissible. However, their donations to their religious institutions are invalid according to many scholars, and it is not permissible to record or document them, as this constitutes an acknowledgment of their reprehensible acts. This differs from their donations to charitable organizations. If your work necessitates recording their religious donations, and you cannot find other employment despite your need, then it is permissible to remain in this job while evading that (recording their religious donations) as much as possible until you find another job.
