Ibn Mas'ud was asked about a man who married a woman and he did not stipulate the dowry for her, and he did not enter into her until he died. So Ibn Mas'ud said: "She gets the same dowry as other women, no less and no more, she has to observe the Iddah, and she gets inheritance." So Ma'qil bin Sinan Al-Ashja'I stood and said: "The Messenger of Allah judged the same as you have judged regarding Birwa bint Washiq, a woman of ours." So Ibn Mas'ud was happy about that.  

عَنْ رَجُلٍ تَزَوَّجَ امْرَأَةً وَلَمْ يَفْرِضْ لَهَا صَدَاقًا وَلَمْ يَدْخُلْ بِهَا حَتَّى مَاتَ فَقَالَ ابْنُ مَسْعُودٍ لَهَا مِثْلُ صَدَاقِ نِسَائِهَا لاَ وَكْسَ وَلاَ شَطَطَ وَعَلَيْهَا الْعِدَّةُ وَلَهَا الْمِيرَاثُ فَقَامَ مَعْقِلُ بْنُ سِنَانٍ الأَشْجَعِيُّ فَقَالَ قَضَى رَسُولُ اللَّهِ ﷺ فِي بِرْوَعَ بِنْتِ وَاشِقٍ امْرَأَةٍ مِنَّا مِثْلَ الَّذِي قَضَيْتَ فَفَرِحَ بِهَا ابْنُ مَسْعُودٍ قَالَ وَفِي الْبَابِ عَنِ الْجَرَّاحِ حَدَّثَنَا الْحَسَنُ بْنُ عَلِيٍّ الْخَلاَّلُ حَدَّثَنَا يَزِيدُ بْنُ هَارُونَ وَعَبْدُ الرَّزَّاقِ كِلاَهُمَا عَنْ سُفْيَانَ عَنْ مَنْصُورٍ نَحْوَهُ
