The Ruling on Working in a Mixed Environment

Question:
Khalid from Riyadh, please go ahead, Khalid. Peace be upon you. And upon you be peace. How are you, Shaykh? May Allah welcome you. We have a question regarding, well, we would like a word and guidance from your eminence about what is happening in some private companies: mixed work between men and women, uncovering, displaying adornment, and breaking the barriers between the two sexes. We hope you will give us guidance on this matter. Is it permissible to work in such a mixed environment? Thank you.

Answer:
The mixing that leads to fitnah (trial, discord or temptation) is forbidden and not permissible, neither in companies nor elsewhere. And whoever sees any of that, he reports it to the men of hisbah (those who enforce public order), who come to look into the reality and address it according to their ability.
And the wrong is not left alone. The mixing between men and women that causes fitnah is the seclusion of a man with a woman, and the travel of a woman without a mahram (a relative one may not marry). All these are means that lead to wrongs, and they are not permissible. The means has the ruling of the end, yes.
