“Cleanliness is half of the faith.” (Prophet Muhammed (s.a.w) (Tirmidhi, Da'wat,86) Islam commands us to be clean,both materially and spiritually. A good Muslim keeps clean his body, clothes, belongings, living place and the world. A good Muslim purifies his soul and keeps his heart and mind clean by being purified from the darkness of evil and the filth of sin.
