It is often claimed that al-Bukhari was the most careful collector of Muslim traditions, omitting thousands of hadiths that did not meet his strict specifications of authenticity. To help illustrate this fact we quote from the Muslim translator of Al-Bukhari's hadith collection:
It has been UNANIMOUSLY AGREED that Imam Bukhari's work is the most authentic of all the other works in Hadith literature PUT TOGETHER. The authenticity of Al-Bukhari's work is such that the religious learned scholars of Islam said concerning him: "The most authentic book after the Book of Allah (i.e., Al-Qur'an) is Sahih Al-Bukhari." .
Before he recorded each Hadith he would make ablution and offer two Rak'at prayer and supplicate his Lord (Allah). Many religious scholars of Islam tried to find fault in the great remarkable collection- Sahih Al-Bukhari, BUT WITHOUT SUCCESS. It is for this reason, they UNANIMOUSLY AGREED that the most authentic book after the Book of AllahIS Sahih Al-Bukhari.
