أَخْبَرَنَا زَكَرِيَّا بْنُ يَحْيَى، قَالَ حَدَّثَنَا عَبْدُ الأَعْلَى بْنُ حَمَّادٍ، قَالَ حَدَّثَنَا مُعْتَمِرُ بْنُ سُلَيْمَانَ، قَالَ حَدَّثَنِي عَبْدُ الرَّزَّاقِ، عَنْ مَعْمَرٍ، عَنِ الزُّهْرِيِّ، عَنْ سَعِيدِ بْنِ الْمُسَيَّبِ، قَالَ غَرَّبَ عُمَرُ رضى الله عنه رَبِيعَةَ بْنَ أُمَيَّةَ فِي الْخَمْرِ إِلَى خَيْبَرَ فَلَحِقَ بِهِرَقْلَ فَتَنَصَّرَ فَقَالَ عُمَرُ رَضِيَ اللَّهُ عَنْهُ لاَ أُغَرِّبُ بَعْدَهُ مُسْلِمًا ‏.‏
