Musnad Ahmad 144:0

Narrated Abu Hashim ibn Utbah: The Messenger of Allah (ﷺ) said to me: "O Abu Hashim, take care of the world, and let the provision of the Hereafter be what is between you and the world, and you will be saved." He also said: "The most wretched of people is he who sells his religion for the world of another."
