«لِفُلَانٍ عِنْدِي أَلْفٌ وَدِيعَةٌ»
“I have one thousand belonging to so-and-so in safekeeping.”
The expression indi (“with me”) may apparently indicate that property is held for another, although another legal characterization remains possible. Adding wadiah (deposit) confirms that the money is held in trust.
A distinction is necessary between indi, describing something in one’s possession, and alayya, generally placing a responsibility upon one. The bare quantity “one thousand” is insufficient to determine the legal implication; the relationship expressed in the sentence matters.
