Narrated Al-Aswad bin Yazid: Mu`adh bin Jabal came to us in Yemen as a tutor and a ruler, and we (the people of Yemen) asked him about (the distribution of the property of ) a man who had died leaving a daughter and a sister. Mu`adh gave the daughter one-half of the property and gave the sister the other half.

حَدَّثَنِي مَحْمُودٌ، حَدَّثَنَا أَبُو النَّضْرِ، حَدَّثَنَا أَبُو مُعَاوِيَةَ، شَيْبَانُ عَنْ أَشْعَثَ، عَنِ الأَسْوَدِ بْنِ يَزِيدَ، قَالَ أَتَانَا مُعَاذُ بْنُ جَبَلٍ بِالْيَمَنِ مُعَلِّمًا وَأَمِيرًا، فَسَأَلْنَاهُ عَنْ رَجُلٍ، تُوُفِّيَ وَتَرَكَ ابْنَتَهُ وَأُخْتَهُ، فَأَعْطَى الاِبْنَةَ النِّصْفَ وَالأُخْتَ النِّصْفَ‏.‏
