The basic objective of Islam is the inner purification of a person. Anything
which hampers this purification should be avoided. We have been sent in this
world to strive to obtain Paradise in the next one. Paradise, as the Qur’ān has specified,
is the abode of pure souls. So if Paradise is our goal, we should always be
heedful to our inner purity.
Keeping this principle in view, it seems that Muslim men and
women swimming together is something which tarnishes the mirror of their souls.
It stimulates base emotions. So Muslim men and women should refrain from it.
