Narrated Ibn 'Abbas:

Allah's Apostle ﷺ said on the day of the conquest of Mecca, "There is no migration now, but there is Jihad (i.e.. holy battle) and good intentions. And when you are called for Jihad, you should come out at once" Allah's Apostle also said, on the day of the conquest of Mecca, "Allah has made this town a sanctuary since the day He created the Heavens and the Earth. So, it is a sanctuary by Allah's Decree till the Day of Resurrection. Fighting in it was not legal for anyone before me, and it was made legal for me only for an hour by daytime. So, it (i.e. Mecca) is a sanctuary by Allah's Decree till the Day of Resurrection. Its thorny bushes should not be cut, and its game should not be chased, its fallen property (i.e. Luqata) should not be picked up except by one who will announce it publicly;
and its grass should not be uprooted," On that Al-'Abbas said, "O Allah's Apostle! Except the Idhkhir, because it is used by the goldsmiths and by the people for their houses." On that the Prophet ﷺ said, "Except the Idhkhir."

حَدَّثَنَا عَلِيُّ بْنُ عَبْدِ اللَّهِ، حَدَّثَنَا جَرِيرٌ، عَنْ مَنْصُورٍ، عَنْ مُجَاهِدٍ، عَنْ طَاوُسٍ، عَنِ ابْنِ عَبَّاسٍ ـ رضى الله عنهما ـ قَالَ قَالَ رَسُولُ اللَّهِ ﷺ يَوْمَ فَتْحِ مَكَّةَ " لاَ هِجْرَةَ وَلَكِنْ جِهَادٌ وَنِيَّةٌ، وَإِذَا اسْتُنْفِرْتُمْ فَانْفِرُوا ". وَقَالَ يَوْمَ فَتْحِ مَكَّةَ " إِنَّ هَذَا الْبَلَدَ حَرَّمَهُ اللَّهُ يَوْمَ خَلَقَ السَّمَوَاتِ وَالأَرْضَ، فَهْوَ حَرَامٌ بِحُرْمَةِ اللَّهِ إِلَى يَوْمِ الْقِيَامَةِ، وَإِنَّهُ لَمْ يَحِلَّ الْقِتَالُ فِيهِ لأَحَدٍ قَبْلِي، وَلَمْ يَحِلَّ لِي إِلاَّ سَاعَةً مِنْ نَهَارٍ، فَهْوَ حَرَامٌ بِحُرْمَةِ اللَّهِ إِلَى يَوْمِ الْقِيَامَةِ، لاَ يُعْضَدُ شَوْكُهُ، وَلاَ يُنَفَّرُ صَيْدُهُ، وَلاَ يَلْتَقِطُ لُقَطَتَهُ إِلاَّ مَنْ عَرَّفَهَا، وَلاَ يُخْتَلَى خَلاَهُ ". فَقَالَ الْعَبَّاسُ يَا رَسُولَ اللَّهِ إِلاَّ الإِذْخِرَ، فَإِنَّهُ لِقَيْنِهِمْ وَلِبُيُوتِهِمْ. قَالَ " إِلاَّ الإِذْخِرَ ".
