This is what the jurists have stated, but perhaps more precise means are now available by which such matters may be tested.
His statement, “and the like,” refers, for example, to a doctor hired to treat a patient. If he arrives to treat the patient and finds that the patient has died, the lease is terminated. If there is another patient in the house and the doctor says, “The patient for whom you summoned me has died, so I will treat the second one and the fee will not be cancelled,” he is not to be granted this; for the subject of the contract was that particular patient, and he is no longer available.
“The lease is not terminated by the death of both contracting parties or of one of them, nor by the loss of the lessee’s maintenance or the like. But if someone rents a house and it collapses, or land for cultivation and its water supply ceases, or it is flooded, the lease is terminated with respect to the remaining period.”
His statement, “not by the death of both contracting parties or of one of them,” means that the lease is not terminated by the death of both parties to the contract, or of one of them, because the subject of the contract remains. Thus, if a person leases his house to someone and then either the lessor or the lessee dies, the lease is not terminated, since it is a binding contract. As is well known, people rent houses: one person dies, another has a child, and so forth. Likewise, if both of them die, the lease is still not terminated, because their respective rights pass to their heirs.
The author previously stated that if the rider dies and leaves no replacement, the lease is terminated—yet the rider is one of the contracting parties. Should we then say that there is a contradiction in his words, or that he followed one view earlier and another view in the second case? The author of al-Insaf adopted the latter explanation, saying that the author of al-Muqniʿ followed one view at the beginning of his discussion and another view in the second case. But in my view, the reconciliation between them is that, in the first case, the rider himself was specified: he said, “I am hiring the camel to travel to Mecca,” and then he died. Here, however, the parties contracted over a specified thing, not a specified individual. Accordingly, the lease is not terminated by the death of both contracting parties or of one of them.
