Who is the author whose saying represents the Madhhab among the Hanafis, similar to Al-Rafi'i and Al-Nawawi among the Shafi'is?

The rules for preferring legal opinions in the Hanafi school are summarized as follows:

1. If Abu Hanifa and his two companions (Abu Yusuf and Muhammad al-Shaybani) agree, it is not permissible to deviate from their opinion. 2. If the Imam agrees with one of his two companions, their opinion is not deviated from. 3. If the Imam holds a solitary opinion while his two companions agree, the Imam's opinion is usually preferred in matters of worship. Abu Yusuf's opinion is preferred in judicial matters, and Muhammad's opinion in matters related to "Dhawi al-Arham" (relatives by blood). 4. If there is no opinion from Abu Hanifa, then Abu Yusuf's opinion is preferred. If not found, then Muhammad's opinion, followed by the opinions of Zufar and Al-Hasan ibn Ziyad.

A Mufti who is not a Mujtahid (independent jurist) may follow this order. However, a Mujtahid chooses what is most strongly supported by evidence in his view.

The most authoritative books in the school are the "Zahir al-Riwayah" books: "Al-Mabsut," "Al-Ziyadat," "Al-Jami' al-Saghir," "Al-Jami' al-Kabir," and "Al-Siyar" by Imam Muhammad al-Shaybani. In addition to "Al-Kafi" by Al-Hakim al-Shahid, and "Al-Mabsut" by Al-Sarakhsi, and other well-known texts such as "Kanz al-Daqa'iq," "Majma' al-Anhur," and "Hashiyat Ibn Abidin." These texts do not transmit rejected or weak opinions.
