البيهقي:٨٦٩١أَخْبَرَنَا أَبُو بَكْرٍ أَحْمَدُ بْنُ الْحَسَنِ الْقَاضِي ثنا أَبُو الْعَبَّاسِ مُحَمَّدُ بْنُ يَعْقُوبَ أنبأ الرَّبِيعُ بْنُ سُلَيْمَانَ أنبأ الشَّافِعِيُّ أنبأ الْقَدَّاحُ عَنِ الثَّوْرِيِّ عَنْ زَيْدِ بْنِ جُبَيْرٍ قَالَ إِنِّي لَعِنْدَ عَبْدِ اللهِ بْنِ عُمَرَ إِذْ سُئِلَ عَنْ هَذِهِ فَقَالَ هَذِهِ حَجَّةُ الْإِسْلَامِ فَلْيَلْتَمِسْ
