What is the ruling on consuming foods that contain unknown or suspicious food additives, or whose permissibility has been indicated without verification, and what is the ruling on selling these foods and consuming what is purchased with their proceeds?

There is no harm in refraining from eating foods that contain Haram ingredients that have not been transformed, such as flavorings and colorings. As for unknown or doubtful ingredients, they are not ruled to be forbidden for sale or consumption, and they remain permissible in principle unless their unlawfulness is overwhelmingly probable. Food is not to be discarded based on doubt, and permissibility is confirmed due to the widespread prevalence of these foods, and the transformation of manufactured substances from their original state through processing. Ibn al-Qayyim reported that the criterion is the description of the thing itself, not its origin, and that the ruling follows the name and description. Sheikh al-Islam Ibn Taymiyyah said that if an impurity is consumed and transformed within permissible things, the good thing that Allah has permitted does not become forbidden. Therefore, it is not forbidden for the questioner to eat or sell something that is unknown or doubtful unless its unlawfulness is overwhelmingly probable, and this is further confirmed if it is labeled as (Halal).
