所谓白银本位（或称银本位），是指白银构成货币单位的基础，享有自由铸造的权利，并且是无限法偿货币。这一本位制在过去广为人知，伊斯兰国家中曾与金本位并行运行。一些国家将其作为主要甚至唯一的货币本位。直到1930年，印度支那地区仍在沿用白银本位，当时银皮阿斯特被金皮阿斯特所取代。

When we talk about the silver standard (or the silver basis), what is meant is that silver forms the basis of the monetary unit, enjoys the freedom of coinage and is an unrestricted legal tender. This standard was well known in the past and was operating in the Islamic State alongside the gold standard. Some countries operated it as their main and only monetary standard. The silver standard continued to be operated in Indo-China until 1930 when the silver piaster was replaced with a golden one.

银本位在所有细节上都与金本位相同。因此，在同一个国家内同时实行金本位和银本位是一件简单的事情。自从真主的使者ﷺ迁往麦地那以来，伊斯兰国家就同时实行金本位和银本位。这一货币政策应当继续以金本位和银本位为基础，即货币应以黄金和白银为本，无论这些货币的流通是使用真正的黄金和白银，还是使用以金银储备为后盾的纸币，也无论这些纸币在何处流通。

The silver standard is just like the gold standard in all its details. Therefore, operating the gold standard alongside the silver standard in the one State is a simple matter. The Islamic State operated the standards of gold and silver together since the Messenger of Allah (pbuh) emigrated to Madinah. This monetary policy should continue to be based on both the gold and the silver standard i.e. money should be in gold and silver, whether the circulation of this money is in real gold and silver or in banknotes backed by reserves of gold and silver wherever these notes are circulated.
