Al-Hasani wal Husseini
The descendant of both Imam Hassan 
and Imam Hussain , the grandsons of the Prophet ﷺ. To quote the Turkish author, Shaikh Muzaffar Ozak Effendi (may Allah bestow His mercy upon him):
The lineage of Sheikh Abdul Qadir is known as the Chain of Gold, since both his parents were descendants of the Messenger ﷺ. His noble father, Abdullah, traced his descent by way of Imam Hassan, while his revered mother, Umm al-Khair, traced hers through Imam Hussain.
