The Ruling on Treating Crops with Harmful Hormones

Question:
Honorable Shaykh, may Allah grant you success. A person works in the agricultural field as an engineer, and he treats his crops with hormones so that they ripen before their time, increase in size, and improve some of their genetic traits. However, it has become clear to him that this treatment causes diseases for the consumer, such as diarrhea and severe allergies. Is it permissible for him to do this, and what are these diseases?

Answer:
It is not permissible, and it is obligatory to prevent the one who causes diseases for people and consumers; he must be prevented and his hands must be restrained. It is forbidden for him to do this. This is from one aspect. The other aspect is that this involves deception; it is deception of the people by making the fruit and produce appear good and healthy due to these treatments, when in fact it is not so. This is not the reality; rather, it is due to falsification. Therefore, it is forbidden on the basis of deception and on the basis of harm.
