(5) باب إِذَا وَجَدَ خَشَبَةً فِي الْبَحْرِ أَوْ سَوْطًا أَوْ نَحْوَهُ
Narrated 'Abdur-Rahman bin Hurmuz:
Abu Hurairah (ra) said, "Allah's Messenger (ﷺ) mentioned an Israeli man." Abu Hurairah then told the whole narration). (At the end of the narration it was mentioned that the creditor) went out to the sea, hoping that a boat might have brought his money. Suddenly he saw a piece of wood and he took it to his house to use as firewood. When he sawed it, he found his money and a letter in it. [See hadith No. 2291 for details]
