ahmad:22639ʿAffān > Ḥammād b. Salamah > Abū Muḥammad b. Maʿbad b. Abū Qatādah > Ibn Kaʿb b. Mālik

[Machine] Abu Qatadah came out to us while we were saying "The Messenger of Allah ﷺ said this and the Messenger of Allah ﷺ said that." So he said, "The faces have changed, do you know what you are saying? I heard the Messenger of Allah ﷺ saying, 'Whoever attributes to me what I have not said should take his seat in hellfire.' A'ffan said, 'And Muhammad ibn Ka'b also said to me...'".  

أحمد:٢٢٦٣٩حَدَّثَنَا عَفَّانُ حَدَّثَنَا حَمَّادُ بْنُ سَلَمَةَ أَخْبَرَنَا أَبُو مُحَمَّدِ بْنُ مَعْبَدِ بْنِ أَبِي قَتَادَةَ عَنِ ابْنِ كَعْبِ بْنِ مَالِكٍ قَالَ

خَرَجَ عَلَيْنَا أَبُو قَتَادَةَ وَنَحْنُ نَقُولُ قَالَ رَسُولُ اللهِ ﷺ كَذَا وَقَالَ رَسُولُ اللهِ ﷺ كَذَا فَقَالَ شَاهَتِ الْوُجُوهُ أَتَدْرُونَ مَا تَقُولُونَ؟ سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ مَنْ قَالَ عَلَيَّ مَا لَمْ أَقُلْ فَلْيَتَبَوَّأْ مَقْعَدَهُ مِنَ النَّارِ قَالَ عَفَّانُ وَقَدْ قَالَ لِي مُحَمَّدُ بْنُ كَعْبٍ
