5330 The immediate occasion was what happened to Khawlah bint Tha'labah, wife of Aws son of Samit. Though in Islam, he divorced her by an old Pagan custom: the formula was known as Zihar, and consisted of the words "Thou art to me as the back of my mother". This was held by Pagan custom to imply a divorce and freed the husband from any responsibility for conjugal duties, but did not leave the wife free to leave the husband's home, or to contract a second marriage. Such a custom was in any case degrading to a woman. It was particularly hard on Khawlah, for she loved her husband and pleaded that she had little children who she had no resources herself to support and whom under Zihar her husband was not bound to support. She urged her plea to the Prophet and in prayer to Allah. Her just plea was accepted, and this iniquitous custom, based on false words, was abolished. See also n. 3670 to
33:4. 5331 For He is a just God, and will not allow human customs or pretences to trample on the just rights of the weakest of His creatures.
