Al-Kāfi - Volume 6 > The Case of a Woman whose Husband Dies before Going to Bed with her and that there is no Waiting Period and Mahr (dower) for her
Hadith #5

عَلِيٌّ عَنْ أَبِيهِ وَ عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ سَهْلِ بْنِ زِيَادٍ عَنِ ابْنِ مَحْبُوبٍ عَنْ عَلِيِّ بْنِ رِئَابٍ عَنْ زُرَارَةَ قَالَ سَأَلْتُهُ عَنِ الْمَرْأَةِ تَمُوتُ قَبْلَ أَنْ يُدْخَلَ بِهَا أَوْ يَمُوتُ الزَّوْجُ قَبْلَ أَنْ يَدْخُلَ بِهَا فَقَالَ أَيُّهُمَا مَاتَ فَلِلْمَرْأَةِ نِصْفُ مَا فَرَضَ لَهَا وَ إِنْ لَمْ يَكُنْ فَرَضَ لَهَا فَلَا مَهْرَ لَهَا .

5. Ali has narrated from his father and a number of our people have narrated from Sahl ibn Ziyad from ibn Mahbub from ibn Ri’ab from Zurarah who has said the following: “I once asked him (the Imam), ‘Alayhi al-Salam, about the case of a woman who dies before his going to bed with her or her husband dies before going to bed with her. He (the Imam) said, ‘Whoever of them dies she deserves one-half of mahr (dower) which is set for her, but if it is not set for her then mahr (dower) is not payable to her.’”
