وَحَدَّثَنَا عَبْدُ بْنُ حُمَيْدٍ، حَدَّثَنَا رَوْحُ بْنُ عُبَادَةَ، ح وَحَدَّثَنِي عَمْرُو بْنُ زُرَارَةَ، أَخْبَرَنَا عَبْدُ الْوَهَّابِ، - يَعْنِي ابْنَ عَطَاءٍ - كِلاَهُمَا عَنْ سَعِيدِ بْنِ أَبِي عَرُوبَةَ، عَنْ قَتَادَةَ، عَنْ أَنَسٍ، عَنِ النَّبِيِّ صلى الله عليه وسلم بِمِثْلِهِ غَيْرَ أَنَّهُ قَالَ ‏
"‏ فَيُقَالُ لَهُ كَذَبْتَ قَدْ سُئِلْتَ مَا هُوَ أَيْسَرُ مِنْ ذَلِكَ ‏"‏ ‏.‏
