(42) باب نَسْخِ مَتَاعِ الْمُتَوَفَّى عَنْهَا بِمَا فُرِضَ لَهَا مِنَ الْمِيرَاثِ
The Qur'anic verse "Those of you who die and leave widows should bequeath for their widows a year's maintenance and residence was abrogated by the verse containing the laws of succession, as one-fourth or one-eighth share was prescribed for them (i.e., the widows). The waiting period for one year was also repealed as a period of four months ten days was prescribed for them.
