Q.) In the environment where I work, women are also working and they offer us sweets, etc. Are we allowed to take it or not?

A.) Shariah has emphasized to maintain strict Hijab with strange women. It is not permissible to maintain a free relationship (all forms of socialization, for example, giving and accepting sweets, etc.) with strange women.

Q.) My friend is a driving instructor. Is he allowed to teach women?

A.) Rasulullah, Sall-Allahu alayhi wa sallam, ordered that a strange male should not be alone with a strange female. In view of the Hadith, it is not permissible for your friend to be alone with strange females and teach them driving.

And Allah Taala Knows Best.
