Fath al-Bari – considered the most prominent and reliable commentary on al-Bukhari's Jami` al-Sahih: In 1414 (817 A.H.), Ibn Hajar commenced the enormous task of assembling his commentary on Sahih Bukhari. Ibn Rajab had begun to write a huge commentary on Sahih Bukhari in the 1390s with the title of Fath al-Bari. Thus, Ibn Hajar decided to name his own commentary with the same title, Fath al-Bari, which in time became the most valued commentary of Sahih Bukhari. When it was finished, in December 1428 (Rajab 842 A.H.), a celebration was held near Cairo, attended by the ulema, judges, and leading Egyptian personalities. Ibn Hajar read the final pages of his work, after which poets recited eulogies and gold was distributed. It was, according to historian Ibn Iyaas (d. 930 A.H.), 'the greatest celebration of the age in Egypt.'
