I don't love her?

Umar ibnul Khattab [r.a.] said to a man who was thinking of divorcing his wife:

“Why do you want to divorce her?” He said, “I do not love her.” ‘Umar RA said, “Must every house be built on love? What about loyalty and appreciation?”

He went on:

'You men! When we marry, we give a serious promise to her. A woman gives birth to children and goes through hard times during her pregnancy. Then she suckles the baby and takes care all nights about her children, when they get sick or need anything. She sacrifices her beauty and youth for being a mother. How fair is if, when her husband leaves her, when she is grown up? If she would have never take care of her home and family, instead of taking care of her body and beauty, her husband would say: “What a bad mother she is.” Where is integrity and loyalty? Fear Allah regarding your behaviour towards your wives.'
