Sahih al-Bukhari - 8

Generally regarded as the single most authentic collection of hadiths, Sahih al-Bukhari covers almost all aspects of life in providing proper guidance from the Messenger of Allah. This book is the work of over 16 years by Imam al-Bukhari who before writing any hadith in this book performed two rak’ahs prayer of guidance from Allah and when he was sure of the hadith’s authenticity, he wrote it in the book.
