مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنْ عَلِيِّ بْنِ الْحَكَمِ عَنْ مُوسَى بْنِ بَكْرٍ عَنْ زُرَارَةَ عَنْ أَبِي جَعْفَرٍ ( عليه السلام ) قَالَ عِدَّةُ الْمُتَوَفَّى عَنْهَا زَوْجُهَا آخِرُ الْأَجَلَيْنِ لِأَنَّ عَلَيْهَا أَنْ تُحِدَّ أَرْبَعَةَ أَشْهُرٍ وَ عَشْراً وَ لَيْسَ عَلَيْهَا فِي الطَّلَاقِ أَنْ تُحِدَّ .
4. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from Ali ibn al-Hakam from Musa ibn Bukayr from Zurarah who has said the following: “Abu Ja’far 
, has said, ‘The waiting period of a widow ends with the end of one of the two which ends last because she must sit in mourning for four months and ten days, while in divorce there is no mourning.’”
