Narrated Ibn 'Umar:

'Umar got some land in Khaibar, and when to the Prophet (ﷺ) and said: I have acquired land in Khaibar which I consider to be more valuable than any I have acquired ; so what do you command me to do with it ? He replied: If you wish, you may make the property as inalienable possession, and give its produce as sadaqah (charity). So 'Umar gave it as a sadaqah declaring that the property must not be sold, given away, or inherited : (and gave its produce as sadaqah to be devoted) to poor, relatives, the emancipation of slaves, Allah's path, travellers. The narrator Bishr added: "and guests". Then the agreed version goes: No sin being committed by the one who administers it if he eats something from it in a reasonable manner, or gives something to a friend, who does not make his own property. The narrator Bishr added: "(provided) he is not storing-up goods (for himself)".

حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا يَزِيدُ بْنُ زُرَيْعٍ، ح وَحَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا بِشْرُ بْنُ الْمُفَضَّلِ، ح وَحَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا يَحْيَى، عَنِ ابْنِ عَوْنٍ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، قَالَ أَصَابَ عُمَرُ أَرْضًا بِخَيْبَرَ فَأَتَى النَّبِيَّ صلى الله عليه وسلم فَقَالَ أَصَبْتُ أَرْضًا لَمْ أُصِبْ مَالاً قَطُّ أَنْفَسَ عِنْدِي مِنْهُ فَكَيْفَ تَأْمُرُنِي بِهِ قَالَ ‏

‏ ‏.‏ فَتَصَدَّقَ بِهَا عُمَرُ أَنَّهُ لاَ يُبَاعُ أَصْلُهَا وَلاَ يُوهَبُ وَلاَ يُورَثُ لِلْفُقَرَاءِ وَالْقُرْبَى وَالرِّقَابِ وَفِي سَبِيلِ اللَّهِ وَابْنِ السَّبِيلِ - وَزَادَ عَنْ بِشْرٍ - وَالضَّيْفِ - ثُمَّ اتَّفَقُوا - لاَ جُنَاحَ عَلَى مَنْ وَلِيَهَا أَنْ يَأْكُلَ مِنْهَا بِالْمَعْرُوفِ وَيُطْعِمَ صَدِيقًا غَيْرَ مُتَمَوِّلٍ فِيهِ ‏.‏ زَادَ عَنْ بِشْرٍ قَالَ وَقَالَ مُحَمَّدٌ غَيْرَ مُتَأَثِّلٍ مَالاً ‏.‏
