There are many narrations of predecessor Masha'ikh approximately 100 years before the birth of Sayyiduna Ghawth al-A'zam Radi Allahu Ta'ala Anho who foretold that shortly there will be born in 'Ajam [non-Arab state] a person who will announce that his foot is on the necks of all the Awliya-Allah. On his announcement, all the Awliya will place their heads under his feet and enter the shadow of his sacred feet.

This is a brilliant proof to undoubtedly confirm that Sayyiduna Shaykh 'Abd al-Qadir Jilani Radi Allahu Ta'ala Anho is the King of all the Qutbs and the Ghawth al-A'zam (most senior Ghawth). [Nuzhat al-Khatir al-Fatir trajuma Sayyidi al-Sharif 'Abd al-Qadir (Manuscript), Page 9-10]
