It was narrated that Ibn 'Umar said:
“Umar bin Khattab said: 'O Messenger of Allah ﷺ, the one hundred shares of the Khaibar I have never been given any wealth that is more beloved to me than them, and I wanted to give them in charity.' The Prophet ﷺ said: 'Make it an endowment and give its produce in the cause of Allah (Subhanahu-wa-Taala).”

حَدَّثَنَا مُحَمَّدُ بْنُ أَبِي عُمَرَ الْعَدَنِيُّ، حَدَّثَنَا سُفْيَانُ، عَنْ عُبَيْدِ اللَّهِ بْنِ عُمَرَ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، قَالَ قَالَ عُمَرُ بْنُ الْخَطَّابِ يَا رَسُولَ اللَّهِ إِنَّ الْمِائَةَ سَهْمٍ الَّتِي بِخَيْبَرَ لَمْ أُصِبْ مَالاً قَطُّ هُوَ أَحَبُّ إِلَىَّ مِنْهَا وَقَدْ أَرَدْتُ أَنْ أَتَصَدَّقَ بِهَا فَقَالَ النَّبِيُّ ﷺ " احْبِسْ أَصْلَهَا وَسَبِّلْ ثَمَرَتَهَا " .
