Abu Dawud Book 12, Hadith Number 2898.

Chapter : Shares of the relatives on the maternal side.

Narated By Buraydah ibn al-Hasib : A man of Khuza’ah died and his estate was brought to the Prophet (PBUH). He said: Look for his heir or some relative. But they found neither heir nor relative. The Apostle of Allah (PBUH) said: Give it to the leading man of Khuza’ah. The narrator Yahya said: Sometimes I heard him (al-Husayn ibn Aswad) say in this tradition: Look for the greatest man of Khuza’ah.
