Muslims commonly use two terms to explain every subject as Halal or Haraam. Halal is a Arabic word which means allowable, lawful with respect to which no restriction exists, and the doing and consuming of which the Law-giver, Allah has permitted.
Halal means the opposite-unlawful that which the Lawgiver completely prohibited; anyone who engages in it is liable to incur the penalty of Allah in the Hereafter as well as a legal punishment in this world.
Halal is universal terms that affect to all facets of life. However, we use these terms only in relation to meat products, food ingredients, cosmetics, food products, personal care products, and food contact materials. There are some things which are not clear are considered questionable or suspect and more information is required to categorize them as Halal or Haram. If a muslim consumes Haram foods and materials, he would be sinful.
Halal in terms of food means that food must be:
