When a woman gets married under Muslim tradition, she is in effect becoming one with her husband. She is saying to him "I want to become so one with you, that we can never ever be separated." She also is saying that she will now be his helper for all eternity, and all eternities, and all eternities combined. She knows that they can never ever be separated, any more than one can separate two jugs of water that have been combined. They are one eternally, and forevermore.
They are in the ether as one heart, they are in the realm of the spirit as one mind, they are in eternity as one soul, and they are in the earth as one body, existing in two separate spirits. There is never a place for divorce in Muslim tradition, only an increasing oneness, a perpetuation of selflessness. Nor is there even a thought of divorce, any more than one can consider separating the two jugs of water. The oneness is irreversible, undeniable, and indefatigable.
