Allama Anwar Shah said about his mastery and deep study on Hadith sciences::

My study and research on Hadith commentary surpasses that of many Hadith commentators. Although, my knowledge on different narrations and different chains of narrations is less than Hafiz Ibn al-Hajar al-Asqalani, but my understanding of the meanings hidden in Hadiths is greater than him and I can comment on Hadith, in respect to its meaning, better than him. On whatever Hadith I comment, I know more than him. Even Hafiz has made mistakes in citing his sources. My commentary would have fewer mistakes than his. Hafiz also lacks the knowledge of some principles of Hadith sciences and I would employ these same principles (in commentary). (Malfuzat-i Muhaddith-i Kashmiri 259-60)
