Is it obligatory for the questioner to leave her job in marketing for stock exchange companies, investments, and forex abroad, based on a dream that she was drinking alcohol, and is it permissible for her to complete the month and take her salary from it?

The ruling on marketing depends on what is being marketed. It is permissible for permissible things and forbidden for forbidden things. It is not permissible to market for companies that involve Sharia violations, such as the stock market and forex systems, which are full of corrupt contracts, except in cases of necessity. The salary earned from a forbidden job, if one was ignorant of its prohibition, is permissible. However, if one was aware of its prohibition, it is not lawful for them to benefit from it, and they must spend it on charitable causes.
