Jurisprudential rulings were not once restricted to anyone. Even if some prominent imams were famous in one science, this does not mean that some of them were not very knowledgeable and well versed in another science, but he did not know much about it, given his fame in the first science in which he emerged. It prevailed over him until he became known only through him, and there are a large number of these people, and among them is our imam, the great critic Yahya bin Ma’in, may God be pleased with him. Many people, and even scholars, know about him except that he is the only imam in jarh and ta’deel, and on his words and the words of his strike are relied upon. In terms of the authenticity and weakness of the hadith, he is in this field the most famous and knowledgeable of fire, and in this field he is the first in it. The insult has meaning, as his words in this art are like cold water to the thirsty person

And the cool Katsim in the days of spring.

This is what is known about the Imam of al-Jarh wal-Ta'deel. As for him being a great jurist and scholar who is diligent, this is what most people do not know. However, he had his own ijtihad, even if they were not as numerous as is the case for the imams of ijtihad and fatwas in terms of number, but he had them. Opinions on a number of jurisprudential issues, and if this indicates anything, it indicates that he worked diligently within a limited scope, given that most of his attention was directed to knowledge.

The first one in which he excelled and emerged was wounding and modification.

This came to my mind and came to my mind to conduct a jurisprudential study of his opinions, after I learned that his book, known as the History of Ibn Ma’in, contains some jurisprudential opinions. This was when I read the book Explanation of the Causes of Al-Tirmidhi. The investigator mentioned in his talk about the most important books in knowing the causes, And Al-Jarh and Al-Ta'deel, so he mentioned that in this book there are some jurisprudential opinions that express the opinion of the jurists of the people of Kufa, then he quoted some of those without mentioning that he was a jurist, so I returned to the history of Ibn Ma'in with a narration.
