The Qur'an and the Sunnah reached us through men who gave their lives to preserving them. This section gathers biographies of the great Imams of Ahlus-Sunnah: the compilers of the Six Books such as Imam Al-Bukhari, Imam Muslim and Imam Abu Dawud, the Imams of fiqh and creed such as Imam Ahmad ibn Hanbal, and the early Tabi'un and hadith masters such as Az-Zuhri, Sa'eed ibn Al-Musayyab and Sufyan ibn 'Uyaynah.

Each biography follows the Imam from his birth and early studies through his journeys, teachers and students, his method in narrating and verifying hadith, his creed, and the praise of the scholars who came after him. Knowing who these men were, and how carefully they worked, lets you read their books with confidence in what you are reading and why it has been trusted for more than a thousand years.
