Sahih al-Bukhari · Book 55: Wills and Testaments (Wasaayaa) · The usufruct of an endowment
Narrated Ibn `Umar:
حَدَّثَنَا أَبُو عَاصِمٍ ، حَدَّثَنَا ابْنُ عَوْنٍ ، عَنْ نَافِعٍ ، عَنِ ابْنِ عُمَرَ ، أَنَّ عُمَرَ ، رضى الله عنه وَجَدَ مَالاً بِخَيْبَرَ، فَأَتَى النَّبِيَّ صلى الله عليه وسلم فَأَخْبَرَهُ، قَالَ " إِنْ شِئْتَ تَصَدَّقْتَ بِهَا ". فَتَصَدَّقَ بِهَا فِي الْفُقَرَاءِ وَالْمَسَاكِينِ وَذِي الْقُرْبَى وَالضَّيْفِ.
`Umar got some property in Khaibar and he came to the Prophet (ﷺ) and informed him about it. The Prophet said to him, "If you wish you can give it in charity." So `Umar gave it in charity (i.e. as an endowment) the yield of which was to be used for the good of the poor, the needy, the kinsmen and the guests.
