A woman leaving the house after Maghrib without a Mahram

Is it haraam, makruh tahrima or makruh tahzihi if a woman goes out of her house after magrib without a mahram and if the distance to be travelled is not safar? or if there is need can she go out on her own? will she be sinful for carring out such an act?
Basically some people say that it is not permissible to go out after magrib without a mahram.
Please clarify.
Jazakala khairan.

Wa Alaikum As Salaam,
If the place she goes to is not the distance that it becomes a safar in shariah, then she will be allowed to go out of her house without a mahram, and she will not be sinful.
However, seeing the times we are living in where there is so much of fitna and immorality, where our Muslim sisters are heckled and teased by men and boys, it is the best and even essential at times that a woman going out of her home at this time be accompanied by a mahram.
And Allah knows best
