His statement, “It is forbidden to resort to legal stratagems in order to eliminate it,” means that it is forbidden for the purchaser to use legal stratagems to eliminate the right of pre-emption. Such stratagems take many forms. One is to make the price appear high: as long as the price is high, the co-owner will not exercise his right of pre-emption. For example, he buys the share for ten thousand but makes it appear that he bought it for twenty thousand. The co-owner does not want it for twenty thousand because the price is too high. This is unlawful. Whenever it becomes clear that the price was ten thousand, he has the right to take it by pre-emption, even after a long time has passed, because a Muslim’s right is not nullified by legal stratagems.
Another example is for the seller to make it appear that he gave it to the purchaser as a gift. It has already been mentioned that, according to the established position of the school, there is no right of pre-emption in respect of what is transferred without consideration. This is therefore a stratagem to eliminate it.
Another example is for the purchaser to make it appear that he has made it an endowment. That is, as soon as he buys it, he says, “It is an endowment for mosques, students of knowledge, or my children.” Once he makes it an endowment, the right of pre-emption is extinguished, because when ownership passes from an owner to a party against which the right of pre-emption cannot be established in the first place, it is extinguished.
In short, resorting to legal stratagems in order to eliminate it is unlawful. The evidence is:
First: the Prophet ﷺ said, “Actions are only by intentions.” (1)
Second: the Prophet ﷺ said, “May Allah curse the Jews: when fat was forbidden to them, they melted it, then sold it and consumed its price.” (2) Thus, they resorted to a legal stratagem to do what had been prohibited.
