So it is deduced from the clear statement of the hadith that whoever buys palm-trees upon where there are pollinated produce, the produce is not included in the sale but rather remains the seller’s property. And it is deduced from its understanding (mafhum) that if they are not then they are included in the sale and are for the buyer. The meaning of the understanding is the opposite understanding (mafhum mukhalafa) which is the understanding of the condition. It is inevitable to adopt this understanding because if the rule of the non-pollinated is the rule of the pollinated then its restriction with the condition is useless speech without any benefit therein. Hence the produce of the palm-tree before follows the palm-tree, and afterwards it does not follow it. However, it is not allowed to sell it until its goodness appears. This is specific to the palm-tree and nothing else is analogised upon it because the pollination is a specific action. The word, even though it is a description, however it is not an understood description for the reason of the rule: so it does not include reasoning. Thus it is not analogised upon due to the absence of the reason, nor is anything joined to it because there is nothing branching from it nor is it something to be analogised upon. Hence the pollination is specific to the palm-tree and it is not in anything else. The palm-tree does not bear it if it is not pollinated. The pollination is fissuration and fertilization and its meaning is to split the blossom of the female palm-tree to reveal therein the blossom of the male palm-tree. It is not said herein that the rule is related to the appearance of produce so that remaining produce is analogised upon that and they are annexed, with the argument that the objective is not the presence of pollination but rather what results thereof which is the appearance of produce. This is not said because the reality in the palm-tree is that the pollination occurs then after the passing of about a month the appearance of produce occurs. If the palm-trees are bought after fecundation, even after one day for example, the contract is valid even if the produce has not appeared. Thus the rule is related to pollination not the appearance of produce so there is no place for analogy due to the absence of the unifying matter. Therefore it is specific to the palm-tree so it is not analogised upon nor is it annexed to.
As for the rule of the remaining trees, it is taken from the understanding of the impermissibility of selling produce before their goodness appears, and the permissibility after their goodness appears. The impermissibility of selling produce before their goodness appears is based upon the meaning that, at that point, the produce follows the tree and it is not isolated from it, so it follows it. The follower is included in the sale together with what it follows even if it is not mentioned in the contract. Accordingly, in other than the palm-tree among all trees, the produce is included in the sale of the tree and follows it if its goodness has not appeared. However, if its goodness appears then it is not included except by mentioning it due to the coming of ahadith indicating the permissibility of selling the produce after its goodness appears which means that it does not follow; so it is not included except by mentioning it. At this point it is allowed to sell it alone or tree only. However if the tree is bought then a wind comes and uproots it or breaks it i.e. if some misfortune happens, there is nothing upon the seller since the sale is completed. Nor has any text come for the reduction of anything from the buyer in this situation. Contrary to the produce if it is sold upon the tree then a misfortune strikes it i.e. blight, then it is obliged upon the seller to reduce the price of the produce of what struck it from the blight. This is due to what ibn Majah narrated from Jabir that the Messenger of Allah (saw) said:
