The Imaam Ibn al-Qayyim may Allaah the Most High bestow His mercy upon him said:
The two books of Ad-Daarimee - an-Naqdh 'alaa Bishr Mareesee (The obliterating Critique Of Bishr al-Mareeseee) and ar-Radd 'Alaa al-Jahmiyyah (The Refutation Of the Jahmites) are from the most splendid books authored regarding the Sunnah (Creed) and from the most beneficial of them. Additionally it is necessary for every student of Sunnah whose goal is to reach the stance of what the Sahaabah and the Taabi'oon and the Imaams were upon is to read his two books.
Furthermore Shaykhul-Islam Ibn Taymiyyah rahimahullah advised with these two books with immense fervor and regarded them in great esteem. In them both is affirmation of at-Tawheed and the Names and Attributes [of Allah] with the use of al-'Aql (Sound reason/intellect) and an-Naql (text from the Book & Sunnah) that which is not found in other than these two [books].
