Mu'adh bought the property of a Jew whose heir was a Muslim. He then narrated from the Prophet (ﷺ) to the same effect.
Sunan Abi Dawud Book 19, Hadith 29
← Previous Hadith I heard the Messenger of Allah (ﷺ) say: Islam increases and does not diminish. He, therefore, appointed a Muslim heir (of a non-Muslim).

Sunan Abi Dawud Book 19, Hadith 28 Next Hadith → The Prophet (ﷺ) said: An estate which was divided in pre-Islamic period may follow the division in force then, but any estate in Islamic times must follow the division laid down by Islam.
