Investing other peoples money for them in non-halal companies

Salam,

Can I invest into non-sharia compliant companies, e.g. that have too much debt, on behalf of other people and take a fee from the profits.

e.g. I take someone’s money, invest in 20 companies of which 8 are not sharia-compliant. Their money grows by £100k, I take £25k as a fee.

Is that allowed to do?

Wasalam

May Allah bless you.
No it is not permissible to do so.

And Allah knows best!
