Fath al-Bari bi Sharh Sahih al-Bukhari (30 Vol)فتح الباري بشرح صحيح البخاري

Fath al-Bari, Sharh Sahih Bukhari was written by al-Hafiz ibn Hajar al-Asqalani, and it is one of the greatest books of hadith interpretation, as well as one of the most comprehensive books that explains Sahih Bukhari. Ibn Hajar spent more than 25 years writing it; he began in 817 AH, when he was 44 years old, and finished in Rajab 842 AH.
It was one of ibn Hajar’s most significant books, one of the most extensive in knowledge, and one of the most beloved among Muslims. He explained Bukhari’s comprehensive Sahih—which Muslims agree is the most accurate book after the book of Allah. He named it “Fath al-Bari in explaining Sahih al-Bukhari,” and it is considered one of Islam’s most important books and an essential source of knowledge. Neither students nor scholars, nor even muftis or mujtahids can do without it. It is hugely important.
