Statement by Hafiz Abu Bakr al-Khallal:

Hafiz Abu Bakr al-Khallal says: "Imam Abu Dawood was the leading Imam of his era. In his time, there was no one superior to him in recognizing the sources of knowledge, understanding the locations of Hadith, and he was unmatched in his piety and God-consciousness." [Tahdhib al-Kamal 11/364]

Statement by Abu Hatim ibn Hibban and Ahmad ibn Muhammad ibn Yasin al-Harawi:

Similarly, Abu Hatim ibn Hibban and Ahmad ibn Muhammad ibn Yasin al-Harawi, among others, have also specifically highlighted his piety and devotion.

An Illustration of the Imam’s Piety and Precaution:

One clear example of the Imam’s piety and caution is that he used to keep one sleeve of his garment wide and the other narrow. When asked about this, he replied: "I keep one sleeve wide so I can store parts of my books in it, while there is no need to make the other one wide."

This act reflects not only his piety and God-consciousness but also his scrupulousness in Hadith transmission and narration.
