Is it permissible for a man to advise a woman in seclusion?

Abu Layla : We have commercial establishments. If we assume we want to advise some of the girls about their clothing or about prayer, is that permissible? For example, if a girl passes by our shop, of course their clothing is not of the type that is "clothed yet naked"... there is complete openness, they do not cover anything, and there is no disturbance for them. If I were to advise her, is it permissible for me to sit with her and advise her? Of course, in the shop itself.

The Shaykh : Alone?
Abu Layli: ...

The Shaykh : I am telling you, no.
Abu Layli: Okay, I am alone in the shop, and people are coming in and going out.

The Shaykh : No, we are afraid for you.
Abu Layli: It is not possible, by the permission of Allah.
Al-Halabi : You say it is not possible...
Abu Layla : I mean, I am always, by the permission of Allah, in a struggle between us and Satan, and always, by the permission of Allah, we are defeating Satan.

The Shaykh : There is blessing in you...

The Shaykh : It is permissible to give you a nudge that sends you down into forms.
Abu Layli: By the permission of Allah, no, by the permission of Allah.
Al-Halabi : You have taken the answer, and that is enough.
Abu Layli: Even if we assume there is an employee in the shop, but he keeps coming in and going out, and then we have customers, meaning they come and go.

The Shaykh : It has to be one person, it has to be a righteous person... and your companion from the jinn. So that he may be an aid for you in the obedience of Allah.
