أَخْبَرَنَا مُحَمَّدُ بْنُ عَبْدِ الأَعْلَى، قَالَ حَدَّثَنَا الْمُعْتَمِرُ، قَالَ سَمِعْتُ مَنْصُورًا، عَنْ إِبْرَاهِيمَ، عَنْ نُبَاتَةَ، عَنْ سُوَيْدِ بْنِ غَفَلَةَ، قَالَ كَتَبَ عُمَرُ بْنُ الْخَطَّابِ إِلَى بَعْضِ عُمَّالِهِ أَنِ ارْزُقِ، الْمُسْلِمِينَ مِنَ الطِّلاَءِ مَا ذَهَبَ ثُلُثَاهُ وَبَقِيَ ثُلُثُهُ .
