Is animal drug testing permissible even though it causes pain and death to many animals? Would it be considered Makrooh or against Islamic ethics?
Torturing or harming animals is not allowed in Islam as we have Hadeeth that a Muslim woman will be punished because she tortured a cat and kept it hungry.
Drug testing can be to save life of human beings but some times it is not for saving life.
It is allowed to use animals in drug testing if it was related to saving human life, but every effort must be done to minimize the suffering of the animals.
Wassalam.
