Should we pay zakaah on valuable things found in an animal’s stomach?

If something valuable is found in an animal’s stomach, should we pay zakaah on it if there is no intention of selling it?

Praise be to Allah, and blessings and peace be upon the Messenger of Allah:

We put this question to Shaykh Muhammad ibn Saalih al-‘Uthaymeen, may Allaah preserve him, who answered as follows:

If it is not gold or silver, there is no zakaah to be paid on it. And Allaah knows best.
