Praise be to Allaah.
The Muslim is supposed to be distinct from non-Muslims in his appearance
and clothing, because this is what Islam says. Also, the Muslim should not wear anything
that is the distinctive clothing of the kuffaar. With regard to neckties, if a person can
do without them, this is better, but if he has to wear them there is nothing wrong with
that, in sha Allaah – but he should make sure that they are not made of natural silk
and that they do not have crosses or pictures of animate creatures on them. And Allaah
knows best.
