Use natural remedies such as cold water to reduce body temperature when having a fever .

This hadith, narrated by Aishah, tells us that fever is caused by the vehement raging of Hell. The Prophet Muhammad (peace be upon him) advised us to cool it down using water. This means that we should use water to reduce our body temperature when we have a fever. We can do this by drinking cold water or taking a bath in cold water. By doing this, we will feel better and our fever will go away faster. This hadith also teaches us about the power of Allah's creation - even something as small as a fever has its origin in the powerful raging of Hell! It reminds us to always remember Allah's greatness and power in all aspects of life.
