It was narrated from Abu Hurairah that : The Prophet said: "Woe to the heels because of Hell-fire".
The Prophet ﷺ was known for his mercy and compassion towards all mankind but he also wanted people to understand that there are consequences for every action they take in life. He wanted them to realize that if they do not follow Allah’s commands then they will have to face severe punishment in the afterlife. This hadith serves as an important reminder for all believers so that they can stay away from sinning and strive towards righteousness instead.
