Marriage is a sacred bond between husband and wife. The Quran speaks about husbands and wives being garments to each other, saying: "Your wives are a garment for you, and you are a garment for them." (Ch.2, v.187)
Think about it. What is a garment? It covers you. It protects you from the elements. It can make you feel beautiful. It is a source of warmth and comfort. But what if your garment is made out of thorns? Thorns dig into your flesh. They hurt you and draw blood. This is what domestic violence does to a marriage. It changes the comfortable garment into a pain-filled thorn-ridden garment.
