The Prophet (peace and blessings be upon him) said: "Allah Almighty has forgiven all hardships, except for the one who takes a loan from a Muslim man unjustly; in that there will be harm upon him and he will be destroyed." They said: Can we seek treatment with such and such thing? The Prophet (peace and blessings be upon him) said: "O servants of Allah! Seek treatment, for Allah Almighty has not sent down any disease except that He has also sent down its cure, except for one disease, that is old age." They said: O Messenger of Allah! Out of all that has been given to man, what is the best thing? The Prophet (peace and blessings be upon him) said: "Good character."

Water has accumulated in my brother’s stomach. I went to the doctors and they told me to cauterize him. Should I cauterize him? The Prophet (peace and blessings be upon him) said:“No! Take him back home.”Then a camel passed by and struck his stomach, so it shrank. He then came back to the Prophet (peace and blessings be upon him), and the Prophet (peace and blessings be upon him) said:“If you had gone to the doctors, you would have started saying that fire cured him.”
