Narrated by 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.
