Sunan Ibn Majah, Volume 4, Book 25, Hadith 3109 (DarusSalam) ⓘ
It was narrated that Safiyyah bint Shaibah said: “I heard the Prophet delivering a sermon in the Year of the Conquest (of Makkah), and he said: ‘O people, Allah made Makkah sacred the day He created the heavens and the earth, and it is sacred until the Day of Resurrection. Its trees are not to be cut, its game is not to be disturbed, and its lost property is not to be taken except by one who will announce it.’‘Abbas said: ‘Except for Idhkhir (a kind of fragrant grass), for it is (used) for houses and graves.’ The messenger of Allah said: ‘Except for Idhkhir.’”
حَدَّثَنَا مُحَمَّدُ بْنُ عَبْدِ اللَّهِ بْنِ نُمَيْرٍ، حَدَّثَنَا يُونُسُ بْنُ بُكَيْرٍ، حَدَّثَنَا مُحَمَّدُ بْنُ إِسْحَاقَ، حَدَّثَنَا أَبَانُ بْنُ صَالِحٍ، عَنِ الْحَسَنِ بْنِ مُسْلِمِ بْنِ يَنَّاقٍ، عَنْ صَفِيَّةَ بِنْتِ شَيْبَةَ، قَالَتْ سَمِعْتُ النَّبِيَّ ـ صلى الله عليه وسلم ـ يَخْطُبُ عَامَ الْفَتْحِ فَقَالَ " يَا أَيُّهَا النَّاسُ إِنَّ اللَّهَ حَرَّمَ مَكَّةَ يَوْمَ خَلَقَ السَّمَوَاتِ وَالأَرْضَ فَهِيَ حَرَامٌ إِلَى يَوْمِ الْقِيَامَةِ لاَ يُعْضَدُ شَجَرُهَا وَلاَ يُنَفَّرُ صَيْدُهَا وَلاَ يَأْخُذُ لُقَطَتَهَا إِلاَّ مُنْشِدٌ " . فَقَالَ الْعَبَّاسُ إِلاَّ الإِذْخِرَ فَإِنَّهُ لِلْبُيُوتِ وَالْقُبُورِ . فَقَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ " إِلاَّ الإِذْخِرَ " .
