What is the ruling on money earned from working in tourism companies that organize tourist trips, and what should the questioner do with the money earned from this work, and is it permissible for him to accept financial assistance from his brother who owns a tourism company?

It is impermissible to work in contemporary tourism due to the objectionable activities it involves, and the earnings derived from it are unlawful. One must repent and dispose of illicit gains by giving them to the poor, the needy, and for public welfare. A poor person in need may take from it according to their necessity. There is no harm in taking money from a brother, even if the source of his wealth is unlawful.
