Is the brother of Imam Ali (as), Jafar, called At-Tayyar and Abbas having wings means they had wings like how Angels were portrayed? Do we have narrations about it?
And is it wrong to draw them with wings?

When Jafars hands were cut off in the battle of Mu’ta, the prophet said Jafar will have wings in paradise so they called him Tayar.

Imams of Ahlulbayt said the same thing about Abbas because his hands were cut off while defending Imam Hussayn.

No it’s not wrong to draw a heavenly image of them in wings.
