Is it permissible to work in a hotel that offers shisha, with shisha constituting a small percentage of its income, given that the job requires one to affirm its availability, direct customers to its location, and collect its price? Is the money earned from this considered unlawful? And what is the ruling on missing congregational prayers and Friday prayers due to the nature of the work, which does not allow one to leave the premises?

If your work in the hotel includes guiding to shisha smoking areas and collecting money from them, then this is impermissible, as it involves assisting in sin. It must be abandoned unless there is a necessity, while avoiding direct involvement in the prohibited act, and seeking a permissible alternative, and advising the owners and visitors of the place. However, if your work is limited to renting rooms and permissible matters, then it is permissible. And missing Friday prayer and congregational prayers is not permissible except out of necessity.
