أَخْبَرَنِي الْمُغِيرَةُ بْنُ عَبْدِ الرَّحْمَنِ، قَالَ حَدَّثَنَا أَحْمَدُ بْنُ أَبِي شُعَيْبٍ، عَنْ مُوسَى بْنِ أَعْيَنَ، عَنْ عَمْرِو بْنِ الْحَارِثِ، عَنْ عَمْرِو بْنِ شُعَيْبٍ، عَنْ أَبِيهِ، عَنْ جَدِّهِ، قَالَ جَاءَ هِلاَلٌ إِلَى رَسُولِ اللَّهِ صلى الله عليه وسلم بِعُشُورِ نَحْلٍ لَهُ وَسَأَلَهُ أَنْ يَحْمِيَ لَهُ وَادِيًا يُقَالُ لَهُ سَلَبَةُ فَحَمَى لَهُ رَسُولُ اللَّهِ صلى الله عليه وسلم ذَلِكَ الْوَادِيَ فَلَمَّا وَلِيَ عُمَرُ بْنُ الْخَطَّابِ كَتَبَ سُفْيَانُ بْنُ وَهْبٍ إِلَى عُمَرَ بْنِ الْخَطَّابِ يَسْأَلُهُ فَكَتَبَ عُمَرُ إِنْ أَدَّى إِلَيْكَ مَا كَانَ يُؤَدِّي إِلَى رَسُولِ اللَّهِ صلى الله عليه وسلم مِنْ عُشْرِ نَحْلِهِ فَاحْمِ لَهُ سَلَبَةَ ذَلِكَ وَإِلاَّ فَإِنَّمَا هُوَ ذُبَابُ غَيْثٍ يَأْكُلُهُ مَنْ شَاءَ ‏.‏

It was narrated from 'Amr bin Shu'aib, from his father that his grandfather said:"Hilal came to the Messenger of Allah with one-tenth of the honey and asked him to protect a valley for him that was called Salabah. 'The Messenger of Allah protected that valley for him. When 'Umar bin Al-Khattab became the Khalifah, sufyan bin Wahb wrote the 'Umar and asked him (about that), and Umar wrote: 'If the gives me what he used to give to the Messenger of Allah, one-tenth of his honey, I will protect Salahab for him, otherwise they are just bees and anyone who wants to may eat of it
