What is the difference between the sound creed (aqeedah) and other creeds such as "al-Tahawiyyah, al-Ash'ariyyah, al-Wasitiyyah, al-Durziyyah, al-Baha'iyyah, and al-Nafsiyyah"? What distinguishes each from the others, why were they given these names, and are there commonalities among them?

The correct creed is the creed of the People of the Sunnah and the Community (Ahl al-Sunnah wal-Jama'ah), disseminated in the texts of the Qur'an and the Sunnah. The imams have compiled it in works called "creeds" (aqaa'id) to facilitate its study, such as "Al-Aqeedah Al-Tahawiyyah" and "Al-Aqeedah Al-Wasitiyyah." As for Druze and Baha'ism, they are other religions besides Islam.
