What is the ruling on working in a cafe that sells sandwiches, juices, and shisha, and what is the ruling on the money earned from this work for ten years?

If the work in a shisha cafe does not involve assisting in serving it, then it is permissible (halal), though it is better to look for another job. However, if the work requires assisting in serving it, then it is forbidden (haram), and one must repent, and dispose of any remaining ill-gotten gains by estimating the earnings from serving shisha and donating them as charity.
