وَإِذَا مَاتَ مَنْ لَهُ الْخِيَارُ بَطَلَ خِيَارُهُ وَلَمْ يَنْتَقِلْ إِلَى وَرَثَتِهِ
Translation: If the person holding this option dies, that particular option terminates and does not pass to the heirs.
This rule concerns this stipulated option. It should not be extended without examination to every kind of option or every financial right.
Example: a buyer reserves a two-day option and dies within that period. His personal khiyar al-shart does not transfer to heirs as the same option.
Other property rights and liabilities must be considered separately under the law of the estate and the contract’s status.
