"‏ 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 ‏.‏ فَقَالَ الَّذِي شَرَى الأَرْضَ إِنَّمَا بِعْتُكَ الأَرْضَ وَمَا فِيهَا - قَالَ - فَتَحَاكَمَا إِلَى رَجُلٍ فَقَالَ الَّذِي تَحَاكَمَا إِلَيْهِ أَلَكُمَا وَلَدٌ فَقَالَ أَحَدُهُمَا لِي غُلاَمٌ وَقَالَ الآخَرُ لِي جَارِيَةٌ ‏.‏ قَالَ أَنْكِحُوا الْغُلاَمَ الْجَارِيَةَ وَأَنْفِقُوا عَلَى أَنْفُسِكُمَا مِنْهُ وَتَصَدَّقَا ‏"

Abu Huraira reported (so many) ahadith of Allah's Messenger (ﷺ), and one of them is this: A person bought from another person a piece of land, and the person who had, bought that land found in it an earthen ware which contained gold. The person who had bought the land said (to the seller of the land): Take your gold from me, for I bought only the land from you and not the gold. The man who had sold the land said: I sold the land to you and whatever was in it. They referred the matter to a person. One who was made as a judge said to them: Have you any issue? One of them said: I have a boy, and the other said: I have a young daughter He (the judge) said: Marry this young boy with the girl, and spend something on yourselves and also give (some) charity out of it.
