Is it permissible to give charity on behalf of a deceased father from money earned by the questioner as an accountant in a tourist hotel, and is this money unlawful?

It is not permissible to work as an accountant in a hotel where immoral acts are committed, or alcoholic beverages are served, or lewd parties are held that involve indecency, dancing, musical instruments, and intermingling, because that constitutes cooperation in sin and transgression. If the hotel is free from these prohibitions, then working in it is permissible. Money earned from forbidden work is not permissible to give in charity because it is ill-gotten wealth, and Allah is good and accepts only what is good.
