Abdul-Qadir Gilani
Sayyid Ahmed Gailani's family are descended from Abdul-Qadir Gilani, the founder of the Qadiriyyah. His father, Sayyid Hasan Gailani, was born in Baghdad before moving to Afghanistan in 1905 in order to establish the Qadiriyyah order in that country. Amir Habibullah Khan gave him land in Kabul and eastern Nangarhar Province.
