All things are considered good except the ones specifically prohibited, which are very few in number and already mentioned in Qur’an and Hadith. Everything is halal unless specifically prohibited. There is no specific mention of altered, modified, genetically engineered food and ingredients in the Quran or the traditions of Prophet Muhammad (S.A.W.), because these scientific developments are very recent. However, genetically modified or engineered products from prohibited animals are prohibited. For example, because pork is prohibited, by extension, any products made from genetically altered pigs are prohibited too.
God is the only one who has the power to legislate for humans.
