أَخْبَرَنَا مُحَمَّدُ بْنُ مُصَفَّى بْنِ بُهْلُولٍ، قَالَ حَدَّثَنَا بَقِيَّةُ، عَنْ سَعِيدِ بْنِ سَالِمٍ الْمَكِّيِّ، عَنْ عُبَيْدِ اللَّهِ بْنِ عُمَرَ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، عَنْ عُمَرَ، قَالَ سَأَلْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم عَنْ أَرْضٍ لِي بِثَمْغٍ قَالَ " احْبِسْ أَصْلَهَا وَسَبِّلْ ثَمَرَتَهَا " .
