author a Sahih was Bukhari [...], followed by Abū al-Ḥusayn Muslim ibn al-Ḥajjāj an-Naysābūrī al-Qushayrī, who was his student, sharing many of the same teachers. These two books are the most authentic books after the Quran. As for the statement of Al-Shafi‘i, who said, "I do not know of a book containing knowledge more correct than Malik's book [Muwatta Imam Malik]," [...] he said this before the books of Bukhari and Muslim. The book of Bukhari is the more authentic of the two and more useful." Ibn al-Salah also quoted Bukhari as having said, "I have not included in the book [Sahih al-Bukhari] other than what is authentic and I did not include other authentic hadith for the sake of brevity." In addition, al-Dhahabi quoted Bukhari as having said, "I have memorized one hundred thousand authentic hadith and two hundred thousand which are less than authentic." Criticism Criticism has also been directed at apparent contradictions within Bukhari regarding the ahruf of the Quran. Some narrations state the Quran was revealed only in the dialect of Muhammad's tribe, the Quraysh, while others state it was revealed in seven ahruf. Certain prophetic medicine and remedies espoused in Bukhari, such as cupping, have been noted for being unscientific. Ibn Hajar al-Asqalani, on the basis of contrary archaeological evidence, criticised a hadith regarding Adam's height and human height. In the 2003 book The Idea of Women in Fundamentalist Islam, Lamia Shehadeh used gender theory to critique an ahaad hadith about women's leadership. Another hadith reported by Abu Hurairah was criticized by Fatema Mernissi for being reported out of context and without any further clarification in the Sahih. The clarification is given in a hadith reported by Aisha in al-Zarkashi's (1344–1392) hadith collection. According to Charles Kurzman, this case raises the question of whether other narrations in Bukhari have been reported incompletely or lack proper context. In 2017, Rachid Aylal, a Quranist, published a book criticizing the Sahih, titled Sahih Al-Bukhari: The End of a Legend. It was banned in Morocco for disturbing spiritual security, due to pressure from Islamists. On August 29, 2022 Ministry of Justice of the Russian Federation has included Sahih al-Bukhari into the federal list of extremist materials (except containing surahs, ayahs and quotes from the Quran) after The Supreme Court of Tatarstan supported the Laishevo District Court's decision to recognize the Sahih as extremist with its appellate ruling of July
