What are the most important books of 'aqidah?

Question:
He says: Please guide us to the books of 'aqidah, and which one should we start with?

Answer:
The important thing is not the selection of the books; the books are accessible and abundant, praise be to Allah. What is important is choosing a teacher who understands 'aqidah correctly, who understands the correct 'aqidah and teaches it. That is the important thing: that you choose a teacher who understands the subject you want and is good at presenting and clarifying it. If you find the teacher, the books are accessible, praise be to Allah. This teacher is the one who will choose the books for you that he will teach and explain to you. However, as a general rule, you should choose the books of the people of the Sunnah and the community. Choose the books of the people of the Sunnah and the community that represent the 'aqidah of the righteous Salaf, such as the books of the early Imams. Like *Kitab al-Sunnah* by al-Ajri, *Kitab al-Sunnah* by Ibn Abi 'Asim, *Sharh Usul Ahl al-Iman* (or *Sharh Usul al-Iman* or *Sharh Usul al-Sunnah*) by al-Ka'i, *Kitab al-Sunnah* by 'Abd Allah ibn Imam Ahmad, and *Kitab al-Sunnah* by al-Khallal. These are old, safe, and good books. There are also books by those who came after them who followed their methodology, such as *Al-'Aqidah al-Tahawiyyah* and its commentary by Ibn Abi al-'Izz. And such as the treatise of Ibn Abi Zayd al-Qayrawani and its commentary. And such as the books of Shaykh al-Islam Ibn Taymiyyah and the books of his student, Imam Ibn al-Qayyim, and al-Hafiz Ibn Rajab.
And the books of Shaykh al-Imam Muhammad ibn 'Abd al-Wahhab (may Allah have mercy on him), and may Allah have mercy on them all. These books follow the methodology of the Salaf, and they contain an explanation of the correct 'aqidah and a warning against what contradicts it. Yes.
