✅ Answer: A "Kanz" or treasure refers to buried wealth that an individual or group discovers beneath the ground.

✅ If the owner or owners of the treasure are identifiable or can be found, their duty is clear. However, in the absence of a known owner, one must consider the following narrations for permission to take ownership:

1⃣عَنِ ابْنِ أَبِی عُمَیْرٍ عَنْ حَمَّادٍ عَنِ الْحَلَبِیِّ فِی حَدِیثٍ قَالَ: سَأَلْتُ أَبَا عَبْدِاللَّهِ عَنِ الْکَنْزِ کَمْ فِیهِ قَالَ الْخُمُسُ

📚 Al-Tahzib, vol. 4, p. 121

In a narration, Halabi reported: I asked Imam Sadiq (peace be upon him) about a treasure and how much is in it. The Imam said: One-fifth (Khums)!

2⃣عَنْ أَحْمَدَ بْنِ مُحَمَّدِ بْنِ أَبِی نَصْرٍ عَنْ أَبِی الْحَسَنِ الرِّضَا قَالَ: سَأَلْتُهُ عَمَّا یَجِبُ فِیهِ الْخُمُسُ مِنَ الْکَنْزِ فَقَالَ مَا یَجِبُ الزَّکَاةُ فِی مِثْلِهِ فَفِیهِ الْخُمُسُ.

📚 Al-Faqih, vol. 2, p. 40

Ahmad ibn Muhammad reported: I asked Imam Ridha (peace be upon him) about the obligatory amount from a discovered treasure for which Khums is necessary. The Imam said: The amount for which Zakat is obligatory is also subject to Khums.

3⃣عَنْ حَمَّادِ بْنِ عَمْرٍو وَ أَنَسِ بْنِ مُحَمَّدٍ عَنْ أَبِیهِ جَمِیعاً عَنِ الصَّادِقِ عَنْ آبَائِهِ فِی وَصِیَّةِ النَّبِیِّ لِعَلِیٍّ قَالَ : یَا عَلِیُّ إِنَّ عَبْدَ الْمُطَّلِبِ سَنَّ فِی الْجَاهِلِیَّةِ خَمْسَ سُنَنٍ أَجْرَاهَا اللَّهُ لَهُ فِی الْإِسْلَامِ إِلَی أَنْ قَالَ وَ وَجَدَ کَنْزاً فَأَخْرَجَ مِنْهُ الْخُمُسَ وَ تَصَدَّقَ بِهِ فَأَنْزَلَ اللَّهُ وَ اعْلَمُوا أَنَّما غَنِمْتُمْ مِنْ شَیْءٍ فَأَنَّ لِلَّهِ خُمُسَهُ الْآیَةَ.

📚 Al-Faqih, vol. 4, p. 365

Imam Sadiq (peace be upon him) narrated from his ancestors that the Prophet Muhammad (peace be upon him and his family) advised Ali (peace be upon him): O Ali! Indeed, Abdul Muttalib established five traditions during the period of ignorance (pre-Islamic era), and Allah continued them in Islam. To the extent that he found a treasure, he took one-fifth of it out and gave it in charity. Therefore, Allah revealed the verse (Quran 8:41): 'And know that anything you obtain of war booty - then indeed, for Allah is one-fifth of it....'

4⃣عَنْ حَمَّادٍ عَنِ الْحَلَبِیِّ قَالَ: سُئِلَ أَبُو عَبْدِ اللَّهِ عَنِ الذَّهَبِ وَ الْفِضَّةِ مَا أَقَلُّ مَا تَکُونُ فِیهِ الزَّکَاةُ قَالَ مِائَتَا دِرْهَمٍ وَ عِدْلُهَا مِنَ الذَّهَبِ.

📚 Al-Kafi, vol. 3, p. 516

Halabi reported: I asked Imam Sadiq (peace be upon him) about the minimum amount of gold and silver that requires Zakat. The Imam said: 200 dirhams and the equivalent in gold!

✅ According to the above narrations and others, if someone finds a treasure on their personal property or land without a known owner, and it is valued at 200 dirhams of silver or more, they are obliged to pay one-fifth (Khums) to the rightful owners, and the remainder can be retained.

اللَّهُمَّ صَلِّ عَلَی مُحَمَّدٍ وَ آلِ مُحَمَّدٍ وَ عَجِّلْ لِوَلِیِّکَ الْفَرَجَ وَ الْعَافِیَةَ وَ النَّصْر
