The Story of the Goat's Head:

Hadhrat Ibn Umar (Radhiyallaho anho) says:

"One of the Sahabah received a goat's head as a present. He thought of a neighbor who had a larger family and was in greater need of it than himself, and presented the same to him. This brother, on receipt of the present, recollected yet another person whom he considered even more deserving than himself, and sent on the head to him. The goat's head is, thus, said to have changed hands no less than seven times, and at last came back to the original person from whom the circulation had started."

We learn from the story how poor and needy the Sahabah usually were, and yet how they indeed preferred others above themselves.
