We read and hear this that Janab Jafar Ibne Abi Talib a.s has been blessed with wings in Paradise and so is Hazrat Abbas a.s.

Question here is are these real wings with which a person can fly or this is in metaphorical sense.

Many scholars believe this is metaphorical. Heaven is beyond what we can imagine, and wings are just a metaphor for this exceptional ability to move in heaven and transport through its dimensions. So these two martyrs have special mobility powers in others that no one else has.
