Giving Haraam Food To Those Who Eat It
I don’t think so but I personally would not be involved in any such transaction at will. However, if something like this (Haram meat) comes in my possession by any chance and there are people who can feed off from it, then its better to feed them instead of wasting it.
What if it was the same scenario but instead of food it was alcohol?
These dietary prohibitions are for you as a Muslim and this rationale though important in understanding the spirit of directive, but is of a secondary nature. You’re free to deny them access to these meals on any ground whether health related or on the basis of ensuring that they stay clean, but that’s your informed decision, the problem only arises when someone declares this act unconditionally Haram from religious perspective without any basis for it.
So- do people have a right from me, that I don’t allow them to do haraam? EG their right is that I never allow them, or aid them to execute an action that would displease the Almighty
