All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad is His slave and Messenger.
We have already issued Fatwa 81425 clarifying the prohibition of different types of commercial insurance. So, if something is forbidden, it is not permissible to help in it by any means as Allaah Says (what means): {Help you one another in virtue, righteousness and piety but do not help one another in sin and transgression.}[Quran 5:2]
Therefore, if this woman receives calls of insurance customers and links them to the insurance companies for renewing the policies and so forth, then this is helping in sin. So, she is obliged to refrain from doing so and if she cannot refrain from doing so, she must leave this job.
However, she is not permitted to continue doing this job except for a necessity. For more benefit on the religious requirements for woman’s work, please refer to Fatwa 83607.
Finally, it should be mentioned that it is not permissible for a Muslim man to have friendship with a non-Mahram woman, as this is a means for evil and corruption.
Allaah Knows best.
