Hasan (may Allah have mercy on him) narrates that the Messenger of Allah (peace and blessings be upon him) said: Surely, in Paradise there will be a bird like a Khurasani camel. A man will come and eat it. Then the bird will go away as if nothing has been diminished from it. So Abu Bakr (may Allah be pleased with him) said: O Messenger of Allah (peace be upon him)! Surely, that bird will be very fat? The Prophet (peace be upon him) said: And the person who eats from it will be even more prosperous. You will be among those who eat from it.
