Single literature is a book written by Al -Bukhari. The book deals with the single Islamic literature contained in the Prophet's Sunnah. The book included some of the sayings of the Companions and the followers. Ibn Hajar stated, "It includes excessive hadiths on what is in the Sahih and has a few of the arrested monuments, which is a lot of benefit." The book is its conditions in the Sahih Book, because the hadiths are hadiths in which there are etiquette and not judgments.
