The fiqh encyclopedia classifies the women forbidden in marriage (al-maharim) whose prohibition is permanent (mu'abbada): seven categories forbidden by blood relation, seven by breastfeeding, four by marriage affinity, the wife struck by li'an (mutual imprecation), the wives of the Prophet (peace be upon him), besides the wisdom of limiting wives to four and the rule on combining two women who are mahram to each other. Each sheet cites the positions of the four schools, the verses and hadiths with their takhrij (Bukhari, Muslim and others) and the classical references. The disputed cases of the daughter born of adultery, the milk engendered by intercourse, and the effect of adultery upon affinity are treated in detail.
