Sunan an-Nasai Book 29, Hadith 3597

أَخْبَرَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ، قَالَ أَنْبَأَنَا أَبُو دَاوُدَ الْحَفَرِيُّ، عُمَرُ بْنُ سَعْدٍ عَنْ سُفْيَانَ الثَّوْرِيِّ، عَنِ ابْنِ عَوْنٍ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، عَنْ عُمَرَ، قَالَ أَصَبْتُ أَرْضًا مِنْ أَرْضِ خَيْبَرَ فَأَتَيْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم فَقُلْتُ أَصَبْتُ أَرْضًا لَمْ أُصِبْ مَالاً أَحَبَّ إِلَىَّ وَلاَ أَنْفَسَ عِنْدِي مِنْهَا ‏.‏ قَالَ ‏ "‏ إِنْ شِئْتَ تَصَدَّقْتَ بِهَا ‏"‏ ‏.‏ فَتَصَدَّقَ بِهَا - عَلَى أَنْ لاَ تُبَاعَ وَلاَ تُوهَبَ - فِي الْفُقَرَاءِ وَذِي الْقُرْبَى وَالرِّقَابِ وَالضَّيْفِ وَابْنِ السَّبِيلِ لاَ جُنَاحَ عَلَى مَنْ وَلِيَهَا أَنْ يَأْكُلَ بِالْمَعْرُوفِ غَيْرَ مُتَمَوِّلٍ مَالاً وَيُطْعِمَ ‏.‏

It was narrated from Sufyan Ath-Thawri, from Ibn 'Awn, from Nafi', from Ibn 'Umar, from 'Umar, that he said:"I was allocated some land of Khaibar. I came to the Messenger of Allah and said: 'I have acquired some land and I have never acquired any wealth that is dearer to me or more precious than it.' He said: 'If you wish, you can give it in charity.'" So he gave it in charity on condition that it would not be bought or given away, for the poor, relatives, slaves, guests and wayfarers. And there is no sin on the administrator if he eats from it or feeds others on a reasonable basis, with no intention of becoming wealthy from it
