Second:

We say: This rests on the assumption that, in the final generation, the condition specifies the amount of the share passing from someone who dies without children to those of his own generation, while the share of someone who dies leaving children is shared by the entire generation. This is rejected on the two grounds already explained.

Third:

Even if we conceded this, it would not constitute using an expression in two different meanings. Rather, it would constitute using a single expression in a single meaning, and thus belong to the category of univocal expressions. The wording explicitly provides for transferring the share of someone who dies without children to his own generation. This provision applies afresh in every clause. Moreover, making transfer to that generation conditional upon the existence of children indicates that he intended succession from individuals to their respective descendants. This is an indication by necessary implication.

When an expression directly signifies one meaning and necessarily implies another, this does not fall within the disputed category, as is the case with most expressions. Its indication of succession from individuals to their respective descendants arises solely from making the generation’s entitlement to the deceased’s share conditional upon his leaving no children. Reason then establishes that, had he intended succession from one generation as a whole to the next as a whole, he would not have imposed this condition, since succession between generations as wholes and the imposition of this condition are incompatible. The incompatibility of these two meanings is a rational proposition understood after conceiving each meaning, because one of the two expressions signifies both by linguistic convention.

This resembles their understanding, from His words:

“His gestation and weaning take thirty months,”

together with His words, exalted is He:

“They shall breastfeed their children for two complete years,”

that the minimum duration of pregnancy is six months. There are many similar examples.
