Hadith 27:157
It was narrated from Ibn 'Abbas, with regard to Allah's saying:
"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.
أَخْبَرَنَا زَكَرِيَّا بْنُ يَحْيَى السِّجْزِيُّ، خَيَّاطُ السُّنَّةِ قَالَ حَدَّثَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ، قَالَ حَدَّثَنَا عَلِيُّ بْنُ الْحُسَيْنِ بْنِ وَاقِدٍ، قَالَ أَخْبَرَنِي أَبِي قَالَ، حَدَّثَنَا يَزِيدُ النَّحْوِيُّ، عَنْ عِكْرِمَةَ، عَنِ ابْنِ عَبَّاسٍ، 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 .
