«لِفُلَانٍ عَلَيَّ أَلْفٌ وَدِيعَةٌ»
“I owe him a thousand, [qualified as] a deposit.”
«لِفُلَانٍ عَلَيَّ أَلْفٌ زُيُوفٌ»
“I owe him a thousand in deficient-quality currency.”
Such qualifications require analysis of whether the later term simply explains the initial description or changes its operative legal significance. Wadiah can affect whether property is held in trust rather than owed as a debt; zuyuf can qualify the grade of currency.
The figure “one thousand” does not settle every question. Legal consequences depend on the relation of the first wording to the later qualifier and whether the latter alters the initial claim.
