Sunan an-Nasa'i, Hadith 3603 ⓘ
It was narrated that Ibn 'Umar said: "Umar said to the Prophet: 'The one hundred shares that I acquired in Khaibar -I have never acquired any wealth that I like more than that, and I want to give it in charity.' The Prophet said: Freeze it and donate its fruits."
أَخْبَرَنَا سَعِيدُ بْنُ عَبْدِ الرَّحْمَنِ، قَالَ حَدَّثَنَا سُفْيَانُ بْنُ عُيَيْنَةَ، عَنْ عُبَيْدِ اللَّهِ بْنِ عُمَرَ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، قَالَ قَالَ عُمَرُ لِلنَّبِيِّ صلى الله عليه وسلم إِنَّ الْمِائَةَ سَهْمٍ الَّتِي لِي بِخَيْبَرَ لَمْ أُصِبْ مَالاً قَطُّ أَعْجَبَ إِلَىَّ مِنْهَا قَدْ أَرَدْتُ أَنْ أَتَصَدَّقَ بِهَا . فَقَالَ النَّبِيُّ صلى الله عليه وسلم " احْبِسْ أَصْلَهَا وَسَبِّلْ ثَمَرَتَهَا " .
