Hadith #2

مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنِ ابْنِ فَضَّالٍ عَنِ ابْنِ بُكَيْرٍ عَنْ عُبَيْدِ بْنِ زُرَارَةَ قَالَ سَأَلْتُ أَبَا عَبْدِ اللَّهِ ( عليه السلام ) عَنْ رَجُلٍ تَزَوَّجَ امْرَأَةً وَ لَمْ يَدْخُلْ بِهَا قَالَ إِنْ هَلَكَتْ أَوْ هَلَكَ أَوْ طَلَّقَهَا فَلَهَا النِّصْفُ وَ عَلَيْهَا الْعِدَّةُ كَمَلًا وَ لَهَا الْمِيرَاثُ .

2. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from ibn Faddal from ibn Bukayr from ‘Ubayd ibn Zurarah who has said the following: “I once asked abu ‘Abd Allah, ‘Alayhi al-Salam, about the case of a man who marries a woman but has not gone to bed with her. He (the Imam) said, ‘If he or she dies or he divorces her, she deserves one- half of the mahr (dower), complete inheritance and must count complete waiting period.’”
