A sister wants to know if becoming a Vegetarian is halal. She doesnt want to reject the blessing from Allah of eating meat at the same time.
You must not make haram on yourself what Allah has made halal for you. Believing that killing animals is cruel to feed upon is disbelief as Allah is the one who allowed us to slaughter such animals and eat them.
If this is a personal choice that has nothing associated with corrupt beliefs as such, you can become a vegan though this is wrong and against the sunnah! You won’t be more merciful than Allah!
