Suppose merchandise was purchased for ten historical coins but those coins ceased circulating before payment. Their aggregate equivalent value was:
On sale date: 1,000 units
On last date of circulation: 800 units
Abu Hanifah: failure of the original sale, with separate restitution consequences.
Abu Yusuf: substitution of value 1,000.
Muhammad: substitution of value 800.
This is a hypothetical valuation example, not a direct ruling on modern currency depreciation.
