Tunapozungumzia kiwango cha fedha (au msingi wa fedha), tunamaanisha kwamba fedha ndiyo msingi wa kitengo cha sarafu, inafurahia uhuru wa kutengeneza sarafu na ni zabuni halali isiyo na vizuizi. Kiwango hiki kilijulikana sana zamani na kilitumika katika Dola ya Kiislamu pamoja na kiwango cha dhahabu. Baadhi ya nchi ziliitumia kama kiwango chao kikuu na pekee cha fedha. Kiwango cha fedha kiliendelea kutumika Indo-China hadi mwaka 1930, ambapo piasta ya fedha ilibadilishwa na ya dhahabu.

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.

Kiwango cha fedha ni sawa kabisa na kiwango cha dhahabu katika maelezo yake yote. Kwa hiyo, kutumia kiwango cha dhahabu pamoja na kiwango cha fedha katika Dola moja ni jambo rahisi. Dola ya Kiislamu ilitumia viwango vya dhahabu na fedha pamoja tangu Mtume ﷺ alipohama kwenda Madina. Sera hii ya fedha inapaswa kuendelea kujengwa juu ya kiwango cha dhahabu na cha fedha pamoja, yaani fedha ya kutumika iwe ya dhahabu na fedha, iwe mzunguko wa fedha hiyo ni dhahabu halisi na fedha halisi, au ni noti za benki zilizoungwa mkono na akiba ya dhahabu na fedha, mahali popote noti hizi zinapozunguka.

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.
