Why is "Al-Aqida al-Tahawiyya" (The Tahawi Creed) called by this name? Is this an overstep concerning the general Islamic creed? And does its naming with this title suggest that it is a separate creed?

The naming of "Al-Aqeedah At-Tahawiyyah" in relation to Imam At-Tahawi is for distinction and to indicate that he compiled its issues. He himself did not name it as such; rather, he called it "The Creed of the People of the Sunnah and the Community," as he mentioned in its introduction: "This is a statement explaining the creed of the People of the Sunnah and the Community, according to the methodology of the jurists of the Muslim nation: Abu Hanifah An-Nu'man ibn Thabit Al-Kufi, Abu Yusuf Ya'qub ibn Ibrahim Al-Ansari, and Abu Abdullah Muhammad ibn Al-Hasan Ash-Shaybani — may Allah be pleased with all of them — and what they believe regarding the fundamentals of religion and what they profess to the Lord of the worlds." This naming was introduced by scholars to differentiate it from other works, and there is no harm in it.
