Approximation of refinement and with the clarification

Authorship / Ibn Hajar Al-Asqalani is a beneficial summary about the narrators, revealing their conditions, and clarifying their traits, and it is one of the most important and famous books on men and criticism and modification. Especially since its author is one of the most famous who wrote in this art, indeed he is the prince of this art and the knight of its field without dispute, as he spent more than twenty years, editing, adding, and modifying, and so on, until it reached us in this form. This book is the culmination of years and years of research and scrutiny, so the author did not pass his judgments on these men randomly or by weighing the words of the trustworthy and the discredited as if they were mathematical equations. No, but it was with insight, patience, and after examining and scrutinizing their hadiths and conditions. So this book has become a reference for many who work in this art. Paper type / Shamua
