Is it permissible to work selling phone calls on a beach full of temptations and scantily clad girls, even without needing the money?

Working in the promotion and sale of phone calls is permissible in Islamic law if it fulfills the conditions of a lawful ijārah (lease/hire contract). However, it is not permissible if it takes place on a beach full of temptations, because in such a situation, the worker will not be safe from falling into sins, witnessing indecencies, and neglecting enjoining good and forbidding evil. The Prophet, peace and blessings be upon him, said: "Indeed, this world is sweet and green, and Allah has made you vicegerents in it and He is looking at how you act. So, beware of this world and beware of women, for the first tribulation of the Children of Israel was concerning women." Therefore, if a permissible act leads with certainty to falling into what is forbidden, then it becomes forbidden, especially when there is no need for the money. And whoever abandons something for the sake of Allah, Allah will compensate him with something better.
