Earning from delivering food with Uber Eats etc.
Q:
1. Is earning from food delivery (Uber Eats, deliveroo, etc.) halaal, when most of the food delivered is not halaal?
2. What's the ruling on haraam earning in the past which a person didn't have knowledge at the time of earning but when he got to know its haraam he stopped that source of earning? Is the haraam earning in the past permissible to keep, even when he didn't have knowledge of it as haraam?
