Primary text

It is not conceded that debt immediately matures upon death. Even if one concedes this, it does not necessitate that the existence of the subject matter at the time of contracting must be stipulated, as doing so would lead to unknowable delivery periods for the salam.

Some jurists argue that the debt maturing upon death necessitates the item's existence at the contract time.
