A man died leaving no heir but a slave whom he had emancipated. The Messenger of Allah (ﷺ) asked: Has he any heir? They replied: No, except a slave whom he had emancipated. The Messenger of Allah (ﷺ) assigned his estate to him (the emancipated slave).
Sunan Abi Dawud Book 19, Hadith 21
← Previous Hadith A man of Khuza'ah died and his estate was brought to the Prophet (ﷺ). He said: Look for his heir or some relative. But they found neither heir nor relative. The Messenger of Allah (ﷺ) 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.
