Shaykh Walead Muhammad Mosaad, Chair & Resident Scholar at the Sabeel Community, covers this epic work (the video below is the first in a YouTube playlist containing all 55 classes) by Shaykh Abd al-Qadir al-Jilani (RAA), al-Fath al-Rabbani.

Sixty-two discourses [Majalis] by Shaikh ‘Abd al-Qadir al-Jilani in the guesthouse [ribat] and the schoolhouse [madrasa] in Baghdad, between the years AH 545 and AH 546. Longer than the discourses of Revelations of the Unseen, these profoundly moving lectures used to be attended by crowds of more than seventy thousand people. As we have been told in the Shaikh’s biography, Necklaces of Gems, more than 400 inkwells would be used in one session by the scribes recording his every word. These discourses cover every aspect of the spiritual path necessary for those who aspire to attain to the nearness of Allah. Adapted from: http://al-baz.com/ourbooks.shtml
