The ruling on women going out to markets without need, and the ruling on the hands of workers in markets touching the hands of women?

Question:
May Allah reward you with good, and may He do you good as well. He says in another case: I work in the same exhibition, and Muslim women and non-Muslim women enter this exhibition. It is necessary to deal with them and speak to them, and sometimes physical contact occurs with their hands. Please guide me, knowing that I am fasting on some days and this happens. Please guide me. May Allah reward you with good.

Answer:
First, we advise these women to fear Allah the Exalted and to protect themselves through hijab and Islamic etiquette. They should not go out to exhibitions or markets except for a pressing need that cannot be met without their going out. If they do go out, they should go out covered and adhering to etiquette, and their going out should be only to the extent of the need, such that when their need is fulfilled, they return to their homes, for the home is their place of safety. Allah the Exalted said: This is for the wives of the Prophet (peace and blessings be upon him), who are the noblest of women and the greatest in trust and religion. So what about other women?
Therefore, they must fear Allah the Exalted and not lead themselves and others into trial. Indeed, the greatest trial that occurred among the Children of Israel was due to women. And he said: So it is obligatory for them to fear Allah the Exalted in themselves and to abandon this roaming in the markets and this repeated going out without need, except for the sake of sightseeing, or to display their adornment to people, or for such and such bad purposes. Then it is obligatory for the guardians of women to fear Allah regarding their women, to protect them, and to prevent them from going out except for a necessary need. They should go out with them to control the matter before it slips from their hands, so that they have care and supervision over their women, for they are shepherds over them and are accountable to Allah for their flock. Then it is obligatory for you, O merchants and owners of exhibitions and workers therein, to have taqwa, the fear of Allah the Exalted, to lower the gaze, and to enjoin good and forbid evil. If you see a woman being lax or causing trial, it is not permissible for you to remain silent about it. Rather, it is obligatory that you disapprove of them and prevent them from this playfulness. You must lower your gaze and not be casual in speech. It is not permissible for a man to touch the hand of a woman who is not lawful for him. It is obligatory for you to restrain your hand and not to touch a non-mahram woman or shake her hand. Indeed, speaking with her without need and suspicious speech is forbidden. So what about touching and shaking hands or the like? Yes.
