Of these, the two considered most accurate are Ṣaḥīḥ al-Bukhārī and Ṣaḥīḥ Muslim, which are called the two sahihs. (The first two, commonly referred to as the Two Sahihs as an indication of their authenticity, contain approximately seven thousand ahadith altogether if repetitions are not counted, according to Ibn Hajar.)
Ṣaḥīḥ al-Bukhārī صحيح البخاري
The Persian scholar al-Bukhārī documented over 300,000 Aḥādīth. Analyzing and comparing all this data, he distilled it to a final compilation of 2,602 Aḥādīth he could conclude without a doubt to be authentic. Basically, he kept only the most accurate and agreed upon 1% of all Aḥādīth. The eminent scholars of the time also agreed on the correctness of his methodology and his final book.
