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 The waiting period for one year was also repealed as a period of four months ten days was prescribed for them.

حَدَّثَنَا أَحْمَدُ بْنُ مُحَمَّدٍ الْمَرْوَزِيُّ، حَدَّثَنِي عَلِيُّ بْنُ الْحُسَيْنِ بْنِ وَاقِدٍ، عَنْ أَبِيهِ، عَنْ يَزِيدَ النَّحْوِيِّ، عَنْ عِكْرِمَةَ، عَنِ ابْنِ عَبَّاسٍ، ‏{‏ وَالَّذِينَ يُتَوَفَّوْنَ مِنْكُمْ وَيَذَرُونَ أَزْوَاجًا وَصِيَّةً لأَزْوَاجِهِمْ مَتَاعًا إِلَى الْحَوْلِ غَيْرَ إِخْرَاجٍ ‏}‏ فَنُسِخَ ذَلِكَ بِآيَةِ الْمِيرَاثِ بِمَا فُرِضَ لَهُنَّ مِنَ الرُّبُعِ وَالثُّمُنِ وَنُسِخَ أَجَلُ الْحَوْلِ بِأَنْ جُعِلَ أَجَلُهَا أَرْبَعَةَ أَشْهُرٍ وَعَشْرًا ‏.‏
