ANSWER:

It’s not limited to food.

Food is just emphasized in hadith. The real condition is that your overall income and spending are halal, which affects the acceptance of dua.

QUESTION: Sheikh, on Islamqa, I was looking at the conditions of accepting dua and one of them was “Ensuring that one’s food comes from permissible sources.” But isn’t the condition everything has to come from halal income, such as getting a haircut or buying a pen,or is it just limited to food?
