What is the ruling on dealing with shops that trade in alcoholic beverages? And what is the ruling on traveling to Sharm El Sheikh and dealing with the commercial establishments there, given the presence of temptations?

If dealing with stores that sell intoxicants is limited to permissible matters only, then there is no harm in it, as the Prophet, peace and blessings be upon him, dealt with Jews and polytheists. As for traveling to the aforementioned village, if you do not feel safe from temptation regarding your religion, then it is not permissible. But if you do feel safe, then there is no harm in traveling for a permissible purpose, though refraining from such dealings is preferable and safer. People will be resurrected on the Day of Judgment according to their intentions, so whoever did not intend what is forbidden will not be held accountable for it.
