Abdullah bin Khubaib narrates from his uncle that we were sitting in a gathering when the Prophet Muhammad (peace be upon him) came, and there were signs of water on his blessed head. We said, "O Messenger of Allah! We see you very happy." The Prophet Muhammad (peace be upon him) said, "Yes!" Then people started talking about wealth, so the Prophet Muhammad (peace be upon him) said, "There is no harm in wealth for the one who fears Allah, but for the one who fears Allah, health is better than wealth, and the happiness of the heart is also a blessing."
