Sahih al-Bukhari · Book 45: Lost Things Picked up by Someone (Luqatah) · If someone finds a thing in the sea
Narrated 'Abdur-Rahman bin Hurmuz:
وَقَالَ اللَّيْثُ حَدَّثَنِي جَعْفَرُ بْنُ رَبِيعَةَ ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ هُرْمُزَ ، عَنْ أَبِي هُرَيْرَةَ ـ رضى الله عنه ـ عَنْ رَسُولِ اللَّهِ صلى الله عليه وسلم أَنَّهُ ذَكَرَ رَجُلاً مِنْ بَنِي إِسْرَائِيلَ ـ وَسَاقَ الْحَدِيثَ ـ "فَخَرَجَ يَنْظُرُ لَعَلَّ مَرْكَبًا قَدْ جَاءَ بِمَالِهِ، فَإِذَا هُوَ بِالْخَشَبَةِ فَأَخَذَهَا لأَهْلِهِ حَطَبًا، فَلَمَّا نَشَرَهَا وَجَدَ الْمَالَ وَالصَّحِيفَةَ " .
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]
