Shaykh 'Abdullah as-Sa'd:

"It's upon the seeker of knowledge to begin, in regard to studying the matters of 'aqīdah and tawhīd, with the book al-Qawā'id al-Arba', followed by Thalāthat-al-Usūl, then Kashf-ash-Shubuhāt, and then Kitāb at-Tawhīd. And the four of them are by Muhammad ibn 'Abd-al-Wahhab, rahimahullahu ta'ālā.

Then, in what relates to the pillars of al-īmān and al-asmā was-sifāt, with the book al-'Aqīdah al-Wāsitiyyah by ibn Taymiyyah, rahimahullah.

Then he reads what Allah makes easy for him of the books of creed, and especially al-Hamawiyyah, at-Tadmuriyyah, Sharh al-Asbahāniyyah, and the first [few] volumes from Majmū' al-Fatāwā of ibn Taymiyyah and from ad-Durar as-Saniyyah of the imāms of the da'wah ('ulama of Najd)."
