Riyad as-Salihin, 1826

Abu Hurairah (May Allah be pleased with him) reported:

The Prophet (ﷺ) said, "A man bought a piece of land from another man, and the buyer found a jar filled with gold in the land. The buyer said to the seller: 'Take your gold, as I bought only the land from you and not the gold.' The owner of the land said: 'I sold you the land with everything in it.' So both of them took their case before a third man who asked: 'Have you any children?' One of them said: 'I have a boy.' The other said, 'I have a girl.' The man said: 'Marry the girl to the boy and spend the money on them; and whatever remains give it in charity."' [Al-Bukhari and Muslim].

وعن أبي هريرة رضي الله عنه أن النبي صلى الله عليه وسلم قال‏:‏ ‏

‏ اشترى رجل من رجل عقاراً، فوجد الذي اشترى العقار في عقاره جرة فيها ذهب، فقال له الذي اشترى العقار خذ ذهبك‏:‏ إنما اشتريت منك الأرض، ولم أشتر الذهب، وقال الذي له الأرض‏:‏ إنما بعتك الأرض وما فيها، فتحاكما إلى رجل، فقال الذي تحاكما إليه‏:‏ ألكما ولد‏؟‏ قال أحدهما ‏:‏ لي غلام، وقال الآخر‏:‏ لي جارية، قال‏:‏ أنكحا الغلام الجارية وأنفقوا على أنفسهما منه وتصدقا‏

‏ ‏(‏‏(‏متفق عليه‏)‏‏)‏‏.‏

Guidance from the Hadith: 1) It points out the merit of religious prudence and abandonment of suspicious wealth, as well as the duty of returning things to those to whom they are due. 2) It urges us to be honest in dealing with others and to give charity in the way of Allah. Benefit: Whatever one buries in a land, like gold or anything else, does not go to the ownership of someone who buys the land; rather, it still belongs to the seller. By contrast, metals naturally existing in the ground are attached to the land itself.
