The terms "mixing" and "mingling" are used frequently in discussions on
the subject of male-female relations in Islam, but these terms were not
used at the time the Qur'an was revealed. However, this does not mean
that such conduct is permissible or that Islam has failed to address the
matter. Islam has detailed the relationship between men and women in the
most precise and exacting terms. It has set down clear guidelines to
show men and women how they must conduct themselves with one another.
From all of this, there can be no question that Islam prohibits the free
mixing of the sexes.
