Halal is what is permitted or lawful according to Islamic Law. The reason of the Creator has stated the lawful things are to preserve mankind from destruction upon themselves and others.
The main concept of halal is free from anything that can harm our religion, our soul, our body, our wealth, and our descendent. These are the five aspects of our lives that we need to take a good care.
Meanwhile, Haram is unlawful, prohibited, or forbidden things or acts according to Islamic Law. Contradict to Halal, the concept of Haram is anything that can bring destruction or harm upon mankind (from five aspects of our lives) and the reason as why the Creator has created the unlawful things is a test to mankind.
