Light of Abu Talib (a.s.) is from the light of the Ahle Bait (a.s.)

Once Ameerul Momineen (a.s.) was seated while there were people around him. A man stood up and said – O Ameerul Momineen – you are in an elevated position while your father is being punished in the Fire (Allah forbid). He (a.s.) retorted – Shut up – may Allah clamp your mouth. By the One who raised Muhammad (s.a.w.a.) with the truth as a Prophet. If my father intercedes for all sinners across the face of the earth, most certainly Allah will accept his intercession. How can my father be punished in the Fire while his son is the distributor of the Heaven and the Fire! By the One who raised Muhammad (s.a.w.a.) with the truth surely Abu Talib’s (a.s.) light on the Day of Resurrection will extinguish all lights except the five lights – light of Muhammad (s.a.w.a.), light of Fatima, light of Hasan (a.s.), light of Husain (a.s.) and light of his infallible sons (a.s.). Surely Abu Talib’s (a.s.) light is from our light. Allah created it two thousand years before Adam.
