This is an encyclopedic site whose objective is to preserve [for present and future generations] classic lectures (mostly from 1990s) by orthodox Muslim speakers who base their lectures on the two primary sources of Islam (Qur'an and Sunnah) and who understand these two sources according to the fahm (comprehension) and application of the Salaf as-Salih (Righteous Predecessors).

Thousands of lectures have been digitized from analog audio cassettes to mp3 format. Many of these lectures are rare and cannot be found anywhere else, online or offline.
