حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا عِيسَى بْنُ يُونُسَ، عَنْ عَبْدِ اللَّهِ بْنِ عَبْدِ الرَّحْمَنِ بْنِ يَعْلَى، عَنْ عَمْرِو بْنِ الشَّرِيدِ، عَنْ أَبِيهِ، قَالَ أَنْشَدْتُ رَسُولَ اللَّهِ ـ صلى الله عليه وسلم ـ مِائَةَ قَافِيَةٍ مِنْ شِعْرِ أُمَيَّةَ بْنِ أَبِي الصَّلْتِ يَقُولُ بَيْنَ كُلِّ قَافِيَةٍ " هِيهِ " . وَقَالَ " كَادَ أَنْ يُسْلِمَ " .
