This indicates that two daughters are entitled to two-thirds of the estate. It is a decisive proof on the very point in dispute and represents the Prophet’s own explanation of the Almighty’s words, “If there are daughters—two or more—they shall receive two-thirds of what he leaves” (Qur’an 4:11). It clarifies the verse’s intent, all the more so because the verse was revealed in connection with Saʿd ibn al-Rabīʿ’s two daughters and their mother’s plea on their behalf; when it was revealed, the Prophet ﷺ sent for their uncle.
Those who maintain that two daughters do not receive the two-thirds share until they are three or more cite the phrase “two or more” as evidence, but this can be answered in several ways. One reply is that the wording simply keeps the parts of the sentence consistent: “Allah instructs you concerning your children: for the male, a share equal to that of two females. If there are daughters—two or more—they shall receive two-thirds of what he leaves” (4:11). The plural verb “are” (kunna) matches the plural “children” when the children happen to be female. Thus, three plurals converge in the verse: the word “children,” the pronoun “are,” and the collective noun “daughters.” Because of these plurals the Qur’an expressed it as “two or more.”
A second answer is that Allah gave the male a portion equal to that of two females. If a single son takes two-thirds while a single daughter takes one-third, it is certain that two daughters together must take two-thirds. If one daughter, in the presence of a son, receives one-third, then all the more reason for her to receive a third when the other co-heir is another daughter. This is an instance of drawing attention from the lesser to the greater. Thus the Almighty stated the share of one daughter explicitly and that of two daughters implicitly; the phrase “two or more” conveys that the fixed share does not increase with an increase in number, even if the daughters exceed two. Allah knows best.
And two granddaughters through a son are treated like direct daughters with respect to the entitlement to two-thirds, whether they are
