Is me promoting a company in the music industry haram

Question

I am an email marketer freelancer by profession, I use email channels to promote products and services.

For some time I've been promoting a company's software that allows people to learn drums and today I started promoting their DRUM kit, I didn't realize that I was promoting a product/service from the music industry until today when I was writing email content for the drum kit.

I want to know if what I have been doing is haram and if yes then what should I do with the money I earned from it.

I have always been steadfast in avoiding companies that are in the haram industry, I've been approached by several clients in the haram industry, and I always outright rejected them but this time I didn't realize it until today.

Can anyone please tell me if what am doing is wrong?

Answer 1

Promotion of Haram is Haram as you are a helping hand for spreading Haram things.

Reffering to [5:2]:

Cooperate with one another in goodness and righteousness, and do not cooperate in sin and transgression. And be mindful of Allah. Surely Allah is severe in punishment.

5:2 clearly states that we should not cooperate in sin. So promotion of drums, piano etc is Haram .

If you have made some money from promotion of Haram you should check what to do with Haram money? to better know what to do with that Haram money.

These type of questions have been asked previously so check them aswell.
