Sahih al-Bukhari 2430

Al-Layth said: Ja'far ibn Rabi'a told me, from Abd al-Rahman ibn Hurmuz, from Abu Hurayra (may Allah be pleased with him), from the Messenger of Allah (peace and blessings be upon him), who mentioned a man from the Children of Israel—and related the hadith. [At its conclusion:] The man went out to see whether a ship might have arrived with his money. Then he found the piece of wood, took it home for firewood, and when he split it open, he found the money and the written note.
