Should I refrain from working in a job related to distributing Pepsi because it is an Israeli product that warrants boycotting?

There is no objection to working for the aforementioned company in what is permissible and unrelated to the forbidden. The fact that one of its products benefits a Jew or an Israeli company does not prohibit working for it. The original Islamic ruling permits commercial dealings between Muslims and non-believers. The boycott of products from a country or company is only preferred due to its hostility towards Muslims, and this ruling is subject to the assessment of benefits and harms by those firmly grounded in knowledge.
