Sayyidina Abu Shurayh Ka’bi (RA) reported that Allah’s Messenger (SAW) said, ‘Indeed, Allah has made Makkah sacred. The people have not made it so. He who believes in Allah and the Last Day must not shed blood here, nor uproot a tree. If anyone cites (my conquest of Makkah) as a leave saying that it was made lawful for Allah’s Messenger (SAW) then Allah made it lawful for me and He did not make it lawful for the people and it was made lawful for me only for a part of the day. Thereafter, it is forbidden till the Day of Resurrection. Then, you, O company of Khuza’ah killed this man of Hudhayl. I am his aaqil (that is, I will pay his blood wit). If, after today, anyone’s man is killed then his people have the choice of two things, either to kill or take bloodwit.”
[Bukhari 1832, Muslim 1354]
