Narrated Abu Shuraih Al-Ka'bi: that the Messenger of Allah ﷺ said: "Indeed Allah made Makkah sacred, it was not made sacred by the people. Whoever believes in Allah, and the Last Day, then let them not shed blood in it, nor cut down any of its trees. If one tries to make an excuse by saying: 'It was made lawful for the Messenger of Allah ﷺ' then indeed Allah made it lawful for me but He did not make it lawful for the people, and it was only made lawful for me for an hour of a day. Then it is returned to being sacred until the Day of Judgement. Then, to you people of Khuza'ah who killed this man from Hudhail: I am his 'Aqil, so whomever (one of his relatives) is killed after today, then his people have two options; either they have him killed, or they take the blood-money from him'."
This hadith teaches us about respecting the sanctity of places like Makkah which are considered holy by Muslims all over the world. It also teaches us about forgiveness and how we should try our best to avoid taking revenge on people who wrong us but rather seek justice through other means such as accepting compensation from them instead. Finally, this hadith reminds us about how important it is for us to respect each other's lives and property so we can live peacefully with one another without resorting to violence or bloodshed whenever there is a disagreement between people.
