that he owes him his wage unconditionally, even if he detains him at a time when he could not benefit from working—for example, if he detains him at night, since the night is not normally a time for work. Nevertheless, it is said that he owes him a wage. The same applies if he is unemployed and does not work. But this issue requires further consideration, for if he detains him while he is unemployed, he has deprived him of nothing. The correct view is that this should be restricted to a person who works, or to a time in which he could benefit from working.
If he detains him and he dies as a result of the detention, is he liable to pay blood money for him? Yes, he is liable to pay blood money, because he died as a result of his detention.
But what if he detains him and a lightning bolt strikes him from the sky? The jurists differed over this issue. Some held that he is liable, because had he not detained him in that place, the lightning bolt would not have struck him. Others held that he is not liable, unless it is known that lightning commonly strikes in that location. If that is the case, then he is liable.
Likewise, if a snake bites him and he dies in the place of detention, we say that he is not liable, unless it is known that snakes are common in that place.
He must return the usurped property together with its increase, even if it costs him several times its value. If he builds on the land or plants in it, he must remove it, compensate for its diminution, restore it to level ground, and pay the rent. …
His statement, “He must return the usurped property,” informs us that the usurper is legally obligated to return the usurped property, and the cost of returning it is borne by the usurper, due to the Prophet’s saying, peace and blessings be upon him: “No wrongful possessor has any right.” (1)
His statement, “together with its increase,” means that if the usurped property increases, that increase belongs to its owner, whether it is attached to it or separate from it, due to the general wording of the author’s statement, “together with its increase.”
