It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that once Sayyiduna Umar Farooq (may Allah be pleased with him) came to the presence of the Messenger of Allah. He saw that the Prophet (peace and blessings be upon him) was sitting on a mat, and its marks had appeared on his blessed side. He said, "O Messenger of Allah! If you had a softer bed made from this, how good it would be!" The Prophet (peace and blessings be upon him) replied: "What do I have to do with the world? My example and the example of the world is like that of a rider who travels all day in the summer, and for a short while takes shade under a tree, then leaves it and moves on."
