Praise be to Allaah.
It is haraam to go to bars
where alcohol is sold, and night clubs which involve immoral and sinful
things. It is not permissible to help anyone with regard to that, or to take
him in his car for free or for payment, because that is helping in sin.
Allaah says (interpretation of the meaning):
“Help you one another in
Al‑Birr and At‑Taqwa (virtue, righteousness and piety); but do not help one
another in sin and transgression. And fear Allaah. Verily, Allaah is Severe
in punishment”
[al-Maa’idah 5:2]
Based on that, if your
husband knows that the passenger wants to go to a haraam place, it is not
permissible for him to take him.
Similarly, he should not
wait for the people who are coming out of those haraam places, because that
is facilitating their coming and going. But if one of them stops him and
asks him to take him home or to some permissible place, he may take him
there, because that does not involve what we have mentioned above about
helping in sin.
