الترمذي:٣٢٦٥حَدَّثَنَا الْحَسَنُ بْنُ قَزْعَةَ الْبَصْرِيُّ حَدَّثَنَا سُفْيَانُ بْنُ حَبِيبٍ عَنْ شُعْبَةَ عَنْ ثُوَيْرٍ عَنْ أَبِيهِ عَنِ الطُّفَيْلِ بْنِ أُبَىِّ بْنِ كَعْبٍ عَنْ أَبِيهِ

عَنِ النَّبِيِّ ﷺَ ( وألْزَمَهُمْ كَلِمَةَ التَّقْوَى ) قَالَ لاَ إِلَهَ إِلاَّ اللَّهُ قَالَ هَذَا حَدِيثٌ غَرِيبٌ لاَ نَعْرِفُهُ مَرْفُوعًا إِلاَّ مِنْ حَدِيثِ الْحَسَنِ بْنِ قَزْعَةَ قَالَ وَسَأَلْتُ أَبَا زُرْعَةَ عَنْ هَذَا الْحَدِيثِ فَلَمْ يَعْرِفْهُ مَرْفُوعًا إِلاَّ مِنْ هَذَا الْوَجْهِ
