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 The waiting period for one year was also repealed as a period of four months ten days was prescribed for them.
بِأَنْ جُعِلَ أَجَلُهَا أَرْبَعَةَ أَشْهُرٍ وَعَشْرًا
"And those of you who die and leave behind wives should bequeath for their wives a year's maintenance and residence without turning them out." This was abrogated by the Verse on inheritance, which allocated to her one-quarter or one-eighth. And the appointed time ('Iddah) of one year was abrogated and replaced with the ('Iddah) term of four months and ten days.
فِي قَوْلِهِ { وَالَّذِينَ يُتَوَفَّوْنَ مِنْكُمْ وَيَذَرُونَ أَزْوَاجًا وَصِيَّةً لأَزْوَاجِهِمْ مَتَاعًا إِلَى الْحَوْلِ غَيْرَ إِخْرَاجٍ } نُسِخَ ذَلِكَ بِآيَةِ الْمِيرَاثِ مِمَّا فُرِضَ لَهَا مِنَ الرُّبُعِ وَالثُّمُنِ وَنَسَخَ أَجَلَ الْحَوْلِ أَنْ جُعِلَ أَجَلُهَا أَرْبَعَةَ أَشْهُرٍ وَعَشْرًا
