The ruling on money earned from work in interior decoration within a shop that violates the Shari'ah?

The questioner : Two weeks ago I asked you about working in a place where the interior decoration violates the Shari'ah. You told me that it is not permissible to work in any place that violates the Shari'ah. So, what is the ruling on the money, my Shaykh?

The Shaykh : ... My brother, let us go outside. And upon you be peace.

The questioner : Two weeks ago, my Shaykh, I asked you about interior decoration in a place that violates the Shari'ah, and you told me it is not permissible. So, what is the ruling on the money I have taken from this shop, while I am still working there?

The Shaykh : The wealth you took—did you know that your work was forbidden?

The questioner : No, of course not, my Shaykh.

The Shaykh : So repent to Allah (Mighty and Majestic) and do not return to what you did.

The questioner : Now, for example, at the end of the job, should I finish the work or not?

The Shaykh : No, do not finish it, do not finish it.

The questioner : So, does it mean, my Shaykh, that I will be fined for these jobs? What should I do?

The Shaykh : You will be fined; you pay the fine from the money you earned by violating the Shari'ah.

The questioner : May Allah reward you with good.

The Shaykh : And you as well.
