حَدَّثَنِي عَنْ مَالِكٍ، عَنْ زَيْدِ بْنِ أَسْلَمَ، عَنْ أَبِيهِ، أَنَّ عُمَرَ بْنَ الْخَطَّابِ، اسْتَعْمَلَ مَوْلًى لَهُ يُدْعَى هُنَيًّا عَلَى الْحِمَى فَقَالَ يَا هُنَىُّ اضْمُمْ جَنَاحَكَ عَنِ النَّاسِ وَاتَّقِ دَعْوَةَ الْمَظْلُومِ فَإِنَّ دَعْوَةَ الْمَظْلُومِ مُسْتَجَابَةٌ وَأَدْخِلْ رَبَّ الصُّرَيْمَةِ وَرَبَّ الْغُنَيْمَةِ وَإِيَّاىَ وَنَعَمَ ابْنِ عَوْفٍ وَنَعَمَ ابْنِ عَفَّانَ فَإِنَّهُمَا إِنْ تَهْلِكْ مَاشِيَتُهُمَا يَرْجِعَا إِلَى نَخْلٍ وَزَرْعٍ وَإِنَّ رَبَّ الصُّرَيْمَةِ وَرَبَّ الْغُنَيْمَةِ إِنْ تَهْلِكْ مَاشِيَتُهُمَا يَأْتِنِي بِبَنِيهِ فَيَقُولُ يَا أَمِيرَ الْمُؤْمِنِينَ يَا أَمِيرَ الْمُؤْمِنِينَ ‏.‏ أَفَتَارِكُهُمْ أَنَا لاَ أَبَا لَكَ فَالْمَاءُ وَالْكَلأُ أَيْسَرُ عَلَىَّ مِنَ الذَّهَبِ وَالْوَرِقِ وَايْمُ اللَّهِ إِنَّهُمْ لَيَرَوْنَ أَنِّي قَدْ ظَلَمْتُهُمْ إِنَّهَا لَبِلاَدُهُمْ وَمِيَاهُهُمْ قَاتَلُوا عَلَيْهَا فِي الْجَاهِلِيَّةِ وَأَسْلَمُوا عَلَيْهَا فِي الإِسْلاَمِ وَالَّذِي نَفْسِي بِيَدِهِ لَوْلاَ الْمَالُ الَّذِي أَحْمِلُ عَلَيْهِ فِي سَبِيلِ اللَّهِ مَا حَمَيْتُ عَلَيْهِمْ مِنْ بِلاَدِهِمْ شِبْرًا ‏.‏

Yahya related to me from Malik from Zayd ibn Aslam from hisfather that Umar ibn al-Khattab gave a mawla of his called Hunayycharge over the hima. He said, "Hunayy! Do not harm the people. Fearthe supplication of the wronged, for the supplication of the wrongedis answered. Let the one with a small herd of camels and the one witha small herd of sheep enter, but be wary of the livestock of Ibn Awfand the livestock of Ibn Affan. If their livestock are destroyed, theywill return to palm-trees and agriculture. If the livestock of the onewith a small herd of camels and the one with a small herd of sheep aredestroyed, he will bring his children to me crying, 'Amir al-muminin!Amir al-Muminin!' Shall I neglect them? Water and pasturage are ofless value to me than gold and silver. By Allah, they think that Ihave wronged them. This is their land and their water. They fought forit in the jahiliyya and became muslims on it in Islam. By He in whosehand my self is! Were it not for the mounts which I give to be riddenin the way of Allah, I would not have turned a span of their land intohima." Translation Not Available
