"The question whether in the particular circumstance the wife shall stand divorced or not is ever so often put alongside the question whether in the analogous circumstance a slave would be freed or not: if in those circumstances, according to some previously settled ‘principle of Islamic jurisprudence’, the slave would be freed, the wife stands divorced; if in those circumstances the slave is to continue in bondage, the wife continues as wife.... That perceptual equivalence—between the wife and the slave—marks the Durr-ul-Mukhtar too. There is not a trace of concern for what shall pass on the wife. The concern is with the power of the husband, the concern is that he should not fall short of having his oath prevail."
