What is the reason for prioritizing a Hadith whose authenticity has not been established over the literal meaning of the Quranic text, which specifies a two-thirds share for more than two daughters, and not just for two daughters?

The share of two daughters is two-thirds, and four proofs indicate this:

1. The Holy Quran: Allah Almighty says: (Allah instructs you concerning your children: for the male, what is equal to the share of two females. But if there are [only] daughters, two or more, for them is two-thirds of what he left. And if there is only one, she will have half.) An-Nisa/11. The point of inference is that if there is one daughter, she gets half, and if there are more than two, they get two-thirds. This indicates by implication (mafhum al-mukhalafa) that two daughters get two-thirds. The word "fawqa" (more than) in the verse might be an additional word meaning "two," or it might mean that if they are denied half and all the wealth, then only two-thirds remain.

2. The Prophetic Sunnah: The hadith of Jabir ibn Abdullah concerning the story of the two daughters of Sa'd ibn Ar-Rabi', where the Prophet (peace be upon him) ordered their uncle to give them two-thirds.

3. Consensus (Ijma'): Scholars have unanimously agreed that the share of two daughters is two-thirds. This has been narrated by Ibn al-Mundhir, Ibn Qudamah, Ibn al-Qattan, Ibn Taymiyyah, and others.

4. Analogical Deduction (Qiyas): By analogy with sisters, as the Quran stipulates that two sisters receive two-thirds in His saying: (But if there are two sisters, they will have two-thirds of what he left) An-Nisa/176. Daughters are more entitled to this because they are closer to the deceased. Similarly, for anyone whose single female inherits half, two of them will inherit two-thirds.
