Aban ibn Abi Ayyash has narrated from Sulaym ibn Qays al Hilali:
Sulaym said: “I heard Salman Farsi saying: “On the Day of Judgment, Iblis will be brought with rein made of fire. ZUFER will be brought with two reins of fire attached.
Iblis will go to him and will scream and say; “May your mother cry for you, who are you? I am the one who involved Awwaleen and Aakhireen in discord but I have only one rein and you have two?”
So he will say: “I am the one who ordered and was obeyed, and I disobeyed God’s command.”
NOTE: Allamah Majlisi (ar) in Bihar, volume 22, page 223 writes:
ZUFER is Umar and HIBTAR is his companion. Because the weight of ZUFER is the same as Umar. HIBTAR means fox, which is very cheating (cunning) – his companion (Abu Bakr) was a cheater (cunning).
