Yahya related to me from Malik that Yahya ibn Said saidthat he had heard al-Qasim ibn Muhammad say that Zayd ibnAbd al-Malik separated some men and their wives who wereslave-girls who had borne children to men who had died,because they had married them after one or two menstrualperiods. He separated them until they had done an idda offour months and ten days. Al-Qasim ibn Muhammad said,"Glory be to Allah! Allah says in His Book, 'Those of youwho die, leaving wives, they are not wives.' "
