The meaning of Iblees

We were told by Ja’far bin Muhammed bin Mas’ud al-‘Ayyashi, from his father, that he said: We were told by Ali bin Hasan bin Ali bin Faddal, that he said: We were told by Muhammed bin Waleed, from Abbas bin Hilal, from Abu’l-Hasan al-Rida, peace be upon him, that he mentioned: The name of Iblees is Harith, and Allah, Exalted and Glorious is He, only says: «O Iblees» (15:32) as in: O disobedient. He was named Iblees [1] because he despaired from the mercy of Allah, Exalted and Glorious is He.
