Narrated Al-Aswad:Mu`adh bin Jabal gave this verdict for us in the lifetime of Allah's Messenger (ﷺ). One-half of the inheritance is to be given to the daughter and the other half to the sister. Sulaiman said: Mu`adh gave a verdict for us, but he did not mention that it was so in the lifetime of Allah's Messenger (ﷺ).
حَدَّثَنَا بِشْرُ بْنُ خَالِدٍ، حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ، عَنْ شُعْبَةَ، عَنْ سُلَيْمَانَ، عَنْ إِبْرَاهِيمَ، عَنِ الأَسْوَدِ، قَالَ قَضَى فِينَا مُعَاذُ بْنُ جَبَلٍ عَلَى عَهْدِ رَسُولِ اللَّهِ صلى الله عليه وسلم النِّصْفُ لِلاِبْنَةِ وَالنِّصْفُ لِلأُخْتِ. ثُمَّ قَالَ سُلَيْمَانُ قَضَى فِينَا. وَلَمْ يَذْكُرْ عَلَى عَهْدِ رَسُولِ اللَّهِ صلى الله عليه وسلم.
