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.'" (Using translation from Tirmidhī 1406)
قَالَ رَسُولُ اللهِ ﷺ يَوْمَ فَتْحِ مَكَّةَ إِنَّ اللهَ ﷻ حَرَّمَ مَكَّةَ وَلَمْ يُحَرِّمْهَا النَّاسُ فَمَنْ كَانَ يُؤْمِنُ بِاللهِ وَالْيَوْمِ الْآخِرِ فَلَا يَسْفِكَنَّ فِيهَا دَمًا وَلَا يَعْضِدَنَّ فِيهَا شَجَرًا فَإِنْ تَرَخَّصَ مُتَرَخِّصٌ فَقَالَ أُحِلَّتْ لِرَسُولِ اللهِ ﷺ فَإِنَّ اللهَ أَحَلَّهَا لِي وَلَمْ يُحِلَّهَا لِلنَّاسِ وَهِيَ سَاعَتِي هَذِهِ حَرَامٌ إِلَى أَنْ تَقُومَ السَّاعَةُ إِنَّكُمْ مَعْشَرَ خُزَاعَةَ قَتَلْتُمْ هَذَا الْقَتِيلَ وَإِنِّي عَاقِلُهُ فَمَنْ قُتِلَ لَهُ قَتِيلٌ بَعْدَ مَقَالَتِي هَذِهِ فَأَهْلُهُ بَيْنَ خِيرَتَيْنِ إِمَّا أَنْ يَقْتُلُوا أَوْ يَأْخُذُوا الْعَقْلَ
