عَنْ زَيْدِ بْنِ ثَابِتٍ رَضِيَ اللَّهُ عَنْهُ أَنَّهُ سُئِلَ عَنْ زَوْجٍ وَأُخْتٍ لِأُمٍّ وَأَبٍ فَأَعْطَى الزَّوْجَ النِّصْفَ وَالْأُخْتَ النِّصْفَ فَكُلِّمَ فِي ذَلِكَ فَقَالَ سَيِّدُنَا رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قَضَى بِذَلِكَ
Sayyiduna Zaid bin Thabit (may Allah be pleased with him) was asked about the inheritance of a deceased woman’s husband and her full sister. So he gave half to the husband and half to the sister. And when he was spoken to about this, he said: Our leader, the Messenger of Allah (peace and blessings be upon him), made this very decision.
