"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  

"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," that he said: "This was abrogated by: 'And those of you who die and leave wives behind them, they (the wives) shall wait (as regards their marriage) for four months and ten days.'"  

عَنْ عِكْرِمَةَ فِي قَوْلِهِ ﷻ { وَالَّذِينَ يُتَوَفَّوْنَ مِنْكُمْ وَيَذَرُونَ أَزْوَاجًا وَصِيَّةً لأَزْوَاجِهِمْ مَتَاعًا إِلَى الْحَوْلِ غَيْرَ إِخْرَاجٍ } قَالَ نَسَخَتْهَا { وَالَّذِينَ يُتَوَفَّوْنَ مِنْكُمْ وَيَذَرُونَ أَزْوَاجًا يَتَرَبَّصْنَ بِأَنْفُسِهِنَّ أَرْبَعَةَ أَشْهُرٍ وَعَشْرًا }
