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
← Previous Hadith The Prophet (ﷺ) said: people of two different religions would not inherit from one another.

Sunan Abi Dawud Book 19, Hadith 27 Next Hadith → Mu'adh bought the property of a Jew whose heir was a Muslim. He then narrated from the Prophet (ﷺ) to the same effect.
