Hazrat Pir Syed Abdul Qadir Jilani recites a famous kalam of Ala Hazrat Imam Ahmed Raza Khan Brelvi (Allah have mercy on him) about the Ahle Bait being noor: "Teri nasal-e-paak mein hain, Bacha bacha noor ka; Tu hai ain-e-noor, Tera sab garana noor ka." Hazrat Pir Syed Abdul Qadir Jilani gives the true explanation of this verse which many of you will probably not know.
