ولا يجوز السلم في الحيوان ولا في أطرافه
Translation: Salam is not permitted in animals or their limbs under this ruling.
Quduri states the classical Hanafi prohibition of salam in living animals. Animals within one nominal kind may differ materially in health, age, strength and other individual qualities that are difficult to control fully by description.
A present sale of one identified animal is not the same as an undertaking to deliver some future, unidentified animal. The passage addresses the latter. Other juristic schools discuss animal salam differently, so the Hanafi rule should not be presented as an undisputed universal position.
