حَدَّثَنَا يَحْيَى بْنُ سَعِيدٍ وَإِسْمَاعِيلُ قَالَا حَدَّثَنَا ابْنُ عَوْنٍ قَالَ يَحْيَى قَالَ حَدَّثَنِي نَافِعٌ عَنِ ابْنِ عُمَرَ أَنَّ عُمَرَ قَالَ يَا رَسُولَ اللَّهِ إِنِّي أَصَبْتُ أَرْضًا بِخَيْبَرَ لَمْ أُصِبْ شَيْئًا قَطُّ هُوَ أَنْفَسَ عِنْدِي مِنْهُ فَقَالَ إِنْ شِئْتَ حَبَسْتَ أَصْلَهَا وَتَصَدَّقْتَ بِهَا قَالَ فَتَصَدَّقَ بِهَا لَا يُبَاعُ أَصْلُهَا وَلَا تُوهَبُ وَلَا تُورَثُ قَالَ فَتَصَدَّقَ بِهَا فِي الْفُقَرَاءِ وَالضَّيْفِ وَالرِّقَابِ وَفِي السَّبِيلِ وَابْنِ السَّبِيلِ لَا جُنَاحَ عَلَى مَنْ وَلِيَهَا أَنْ يَأْكُلَ بِالْمَعْرُوفِ أَوْ يُطْعِمَ صَدِيقًا غَيْرَ مُتَمَوِّلٍ فِيهِ
مسند امام احمد بن حنبل · Hadith 5179
It was narrated from Ibn 'Umar that 'Umar said: O Messenger of Allah (PBUH), I have been given a share of land at Kbaybar and I have never been given any wealth that is more precious to me than it. He said: "If you wish, you can 'freeze' it and give it in charity." So 'Umar gave it in charity and stipulated that it was not to be sold, given as a gift or inherited, and he gave it in charity to the poor, guests and slaves, for the sake of Allah (i.e., jihad) and for wayfarers; there was no sin on the one appointed to look after it if he ate from it on a reasonable basis, and fed a friend without storing anything for the future.
