Sahih al-Bukhari 3472, Book 60, Hadith 139

Allah's Messenger said, "A man bought a piece of and from another man, and the buyer found an earthenware jar filled with gold in the land. The buyer said to the seller. 'Take your gold, as I have bought only the land from you, but I have not bought the gold from you.' The (former) owner of the land said, "I have sold you the land with everything in it.' So both of them took their case before a man and requested him to decide as an arbitrator. The arbitrator asked, 'Do you have children?' One of them said, "I have a boy.' The other said, "I have a girl.' The arbitrator said, 'Marry the girl to the boy and spend the money on both of them and give the rest of it in charity.'"

حَدَّثَنَا إِسْحَاقُ بْنُ نَصْرٍ، أَخْبَرَنَا عَبْدُ الرَّزَّاقِ، عَنْ مَعْمَرٍ، عَنْ هَمَّامٍ، عَنْ أَبِي هُرَيْرَةَ ـ رضى الله عنه ـ قَالَ قَالَ النَّبِيُّ صلى الله عليه وسلم ‏ "‏ اشْتَرَى رَجُلٌ مِنْ رَجُلٍ عَقَارًا لَهُ، فَوَجَدَ الرَّجُلُ الَّذِي اشْتَرَى الْعَقَارَ فِي عَقَارِهِ جَرَّةً فِيهَا ذَهَبٌ، فَقَالَ لَهُ الَّذِي اشْتَرَى الْعَقَارَ خُذْ ذَهَبَكَ مِنِّي، إِنَّمَا اشْتَرَيْتُ مِنْكَ الأَرْضَ، وَلَمْ أَبْتَعْ مِنْكَ الذَّهَبَ‏.‏ وَقَالَ الَّذِي لَهُ الأَرْضُ إِنَّمَا بِعْتُكَ الأَرْضَ وَمَا فِيهَا، فَتَحَاكَمَا إِلَى رَجُلٍ، فَقَالَ الَّذِي تَحَاكَمَا إِلَيْهِ أَلَكُمَا وَلَدٌ قَالَ أَحَدُهُمَا لِي غُلاَمٌ‏.‏ وَقَالَ الآخَرُ لِي جَارِيَةٌ‏.‏ قَالَ أَنْكِحُوا الْغُلاَمَ الْجَارِيَةَ، وَأَنْفِقُوا عَلَى أَنْفُسِهِمَا مِنْهُ، وَتَصَدَّقَا ‏" ‏‏.‏
