البيهقي:٢٠٩٦٩أَخْبَرَنَا أَبُو الْحُسَيْنِ بْنُ بِشْرَانَ أنبأ الْحُسَيْنُ بْنُ صَفْوَانَ ثنا عَبْدُ اللهِ بْنُ مُحَمَّدِ بْنِ أَبِي الدُّنْيَا ثنا عُبَيْدُ اللهِ بْنُ عُمَرَ ثنا حَمَّادُ بْنُ زَيْدٍ عَنْ أَيُّوبَ عَنْ نَافِعٍ عَنْ صَفِيَّةَ أَنَّ ابْنَ عُمَرَ دَخَلَ عَلَى بَعْضِ أَهْلِهِ وَهُمْ يَلْعَبُونَ بِهَذِهِ الشَّهَارَدَةِ فَكَسَرَهَا قَالَ

وَسَمِعْتُ حَمَّادًا مَرَّةً يَقُولُ كَسَرَهَا عَلَى رَأْسِهِ
