حَدَّثَنَا أَحْمَدُ بْنُ يُونُسَ، قَالَ‏:‏ حَدَّثَنَا زُهَيْرٌ، قَالَ‏:‏ حَدَّثَنَا مَنْصُورٌ، عَنْ رِبْعِيِّ بْنِ حِرَاشٍ، قَالَ‏:‏ حَدَّثَنَا أَبُو مَسْعُودٍ عُقْبَةُ قَالَ‏:‏ قَالَ النَّبِيُّ صلى الله عليه وسلم‏:‏ إِنَّ مِمَّا أَدْرَكَ النَّاسَ مِنْ كَلاَمِ النُّبُوَّةِ‏:‏ إِذَا لَمْ تَسْتَحِ فَاصْنَعْ مَا شِئْتَ‏.‏
