Allah, the Most High loves the person who is clean, and people respect him. This is because cleanliness is a part of Faith. Faith has levels, and the highest of them is the statement "None has the right to be worshipped except Allah," while the lowest of them is removing harmful things from the road.
For this reason, cleanliness is from the matters which Islam encourages to be maintained. Thus Islam has legislated for us ablution for every prayer, and bathing for Jumu'ah (Friday) and the Eids (celebrations). Islam calls upon us to be clean of body, heart and mind, in our homes, our gatherings, and the road. Our Messenger, Muhammad, was the best example of cleanliness. He was the cleanest of people, both outwardly and inwardly. He was known amongst the people by his nice smell, his handsome clothing, and his pure character. All of this is because cleanliness is from Faith. It keeps the body active and purifies it. It protects the body from sickness and illness. The clean Muslim is a beautiful picture for his religion, and a handsome representation for his family.
Why don't we behave with cleanliness in our bodies, our clothing and our hearts? (Purification of the heart means purifying it from jealousy, hatred, malice and deception.)
Why don't we behave with this beautiful mannerism (cleanliness) in our homes, streets and stores?
We will do it, and our children will do it if we give a little thought about it, and that is the purpose for the presentation of this book.
I hope that we will learn and adopt the things we read from the manners of Islam.
