Is it permissible to impose conditions on workers?

The questioner:
I have a private business, and this business has secrets that I keep. I have imposed two conditions on the workers who work with me: first, that they never disclose the secrets of this business, and second, that they do not engage in this business if they leave my employment. Is this permissible?

The Shaykh:
Yes, Muslims are bound by their conditions. As long as you have imposed these conditions on them, and you would suffer harm if they disclosed this business or practiced it outside the scope of your work, and you have suffered harm in this regard, and you have imposed these conditions on them, Muslims are bound by their conditions. It is not permissible for them to do this. Yes.

The presenter:
May Allah reward you, the questioner says

The questioner:
If one of the Asha'irah callers.

The Shaykh:
That this business be lawful. However, if it is a forbidden secret, then this is not permissible. Except if the condition makes a forbidden thing lawful or a lawful thing forbidden, then this is not permissible. Yes.
