If the thing usurped by a person which has perished is like wheat and barley...
If the thing usurped by a person which has perished is like wheat and barley, which has much peers similar to it in characteristics affecting the demands, he (the usurper) should pay a thing which is similar to the one usurped by him. However, the quality of that replacement should be the same as of the thing which has been usurped and has perished. For example, if he has usurped rice of superior quality, he cannot replace it with a rice of inferior quality.
If the thing usurped by a person is usurped from him by another person and it perishes, the owner of the thing can take its compensation from any one of them, or can demand a part of the compensation from each of them. And if he takes compensation for the thing from the first usurper, the first usurper can demand whatever he has given from the second usurper. But if he is compensated by the second usurper, that second usurper cannot demand what he has given, from the first usurper.
Rules of the Lost Property When Found Any lost property other than an animal, which does not bear any sign by means of which it may be possible to locate its owner, irrespective of whether its value is less than a Dirham (12.6 peas of coined silver) or not, can be kept for himself by one who finds it, but the recommended precaution is that he gives it away as Sadaqah on behalf of the owner, whoever he may be. The same rule applies for money which has not any sign.
But if there is signs like quantity or characteristics of time and place for the money found, one should announce it as mentioned in the following rule.
If a person finds something which bears a sign by means of which its owner can be located, and even if he comes to know that its owner is a non-Muslim whose property must be protected, and if the value of that thing reaches one Dirham, he should make an announcement about it at the place of gathering of the people for one year from the day on which he finds that thing, and if its value is less than one Dirham, the person who finds it should, as an obligatory precaution, give it away as Sadaqah on behalf of the owner, whoever he may be.
And when the owner is found, the replacement should be given to him, if he does not approve the Sadaqah given on his behalf.
