The Prophet used to eat on the ground, and sat like a slave. He repaired his shoe with his hand, and patched his clothes with his hand. He would ride an unsaddled ass and would seat someone behind him. If there was a curtain on his door with pictures on it he would say to one of his wives. "O' such-and-such, take it away out of my sight because if I look at it I recall the world and its allurements." Thus, he removed his heart from this world and destroyed its remembrance from his mind.
