Is it unlawful to work as a human resources manager in a company that exports animal intestines—including 10% pig intestines—and is it permissible to give 10% of one's salary as charity to purify the money, given the possibility of finding another job with a significantly lower salary?

It is not permissible to work for this company because its work involves both impermissible activities, such as selling pork and its derivatives, and permissible ones, such as selling lamb and beef. The questioner's work in bringing workers for both fields is considered assisting in sin, which is forbidden as stated in the verse: "And cooperate in righteousness and piety, but do not cooperate in sin and aggression" (Quran 5:2). Furthermore, commercial insurance is prohibited due to its inclusion of gharar (excessive uncertainty) and maysir (gambling). Therefore, the questioner must leave this job and seek another without any doubt concerning its permissibility. As for the salary earned from the impermissible work, he must estimate the impermissible portion and donate it as charity to clear his conscience.
