فَإِنْ قَبَضَهُ الْمُشْتَرِي فَهَلَكَ فِي يَدِهِ ضَمِنَهُ بِالْقِيمَةِ
Translation: If the buyer takes possession and the object perishes in his hands, he must compensate its value.
Quduri uses bi-l-qimah, meaning compensation according to the legally assessed value. It does not say bi-l-thaman here.
Example: the agreed selling price is Rs 8,000, while the property has an assessed value of Rs 7,000. If it perishes in the buyer’s custody during the seller’s option, the rule directs attention to value liability, not automatically the contract price.
Actual assessment and surrounding facts require separate verification.
