“I hear Abū ʿAbdillāh (a) saying, ‘A man came to visit the Prophet (ṣ) while he was sitting on a mat which had left marks on his body, and a pillow made of palm fibers which had left a mark on his cheek. So he began wiping [his blessed face] saying, “Chosroes and Caesar would never be pleased with such [for themselves]. They sleep on silk and brocade while you are on this mat!” So the Messenger of Allah (ṣ) said, “I am surely better than both of them by Allah, I am surely more noble than them both by Allah! What do I have to do with this world? Indeed the example of this world is but like a man who rides past a tree that has a shadow, so he takes shade under it. When the shadow recedes, he departs and leaves it.”’”
