The Prophet (صلى الله عليه وسلم) said in a hadith reported by Imām Muslim in his Sahih:
“That I have not
left a fitnah greater than the fitnah of women after me.”

Imām ibn Qayyim (رحمه الله) continues: That there is
no doubt that allowing intermingling of women with men is from the root of
tribulation and evil in societies. It is from the foremost reasons for the
descent of the punishment of Allāh upon the people, and it
is a cause for the general corruption in society, and likewise individual
corruption i.e. that general corruption in society are from the crimes that are
committed as a result of that, and specific corruption with regards to the
lives of individuals that marriages fall apart, that a man no longer knows how
to respect the honour of his daughter, and individual corruption within homes
occurs because of this. This is because we do not protect ourselves as men, and
we do not protect our womenfolk from free-mixing. Imām ibn Qayyim (رحمه الله) mentions: that
the free-mixing with men results in an increase in lewd behaviour, fornication
and adultery.
