Sunan an-Nasa'i, Volume 4, Book 27, Hadith 3554 (DarusSalam) ⓘ

It was narrated from Ibn Mas'ud, that he was asked about a man who married a woman, but did not name a Mahr or consummate the marriage before he died. Ibn Mas'ud said: "She should have a Mahr like that of women like her, no less and no more; she has to observe the 'Iddah, and she is entitled to inherit." Ma'qil bin Sinan Al-Ashja'i stood up and said: "The Messenger of Allah passed a similar judgment among us concerning Birwa' bint Washiq." And Ibn Masud rejoiced at that.

أَخْبَرَنَا مَحْمُودُ بْنُ غَيْلاَنَ، قَالَ حَدَّثَنَا زَيْدُ بْنُ الْحُبَابِ، قَالَ حَدَّثَنَا سُفْيَانُ، عَنْ مَنْصُورٍ، عَنْ إِبْرَاهِيمَ، عَنْ عَلْقَمَةَ، عَنِ ابْنِ مَسْعُودٍ، أَنَّهُ سُئِلَ عَنْ رَجُلٍ، تَزَوَّجَ امْرَأَةً وَلَمْ يَفْرِضْ لَهَا صَدَاقًا وَلَمْ يَدْخُلْ بِهَا حَتَّى مَاتَ قَالَ ابْنُ مَسْعُودٍ لَهَا مِثْلُ صَدَاقِ نِسَائِهَا لاَ وَكْسَ وَلاَ شَطَطَ وَعَلَيْهَا الْعِدَّةُ وَلَهَا الْمِيرَاثُ ‏.‏ فَقَامَ مَعْقِلُ بْنُ سِنَانٍ الأَشْجَعِيُّ فَقَالَ قَضَى فِينَا رَسُولُ اللَّهِ صلى الله عليه وسلم فِي بِرْوَعَ بِنْتِ وَاشِقٍ - امْرَأَةٍ مِنَّا - مِثْلَ مَا قَضَيْتَ ‏.‏ فَفَرِحَ ابْنُ مَسْعُودٍ رضى الله عنه ‏.‏
