Ruling on the imported margarine

The basic ruling regarding things is their permissibility until prohibition is proven. If there is doubt regarding the lawfulness of a certain food, it is best as a precautionary measure not to consume it. This is based on the Hadith in which the Prophet (peace be upon him) said, "Leave what causes you doubt to what does not cause you doubt." However, a person should not order others to abstain from consuming this type of food. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
