حَدَّثَنِي عَمْرُو بْنُ مُحَمَّدِ بْنِ بُكَيْرِ بْنِ مُحَمَّدٍ النَّاقِدُ حَدَّثَنَا إِسْمَاعِيلُ ابْنُ عُلَيَّةَ عَنْ سَعِيدٍ الْجُرَيْرِيِّ حَدَّثَنَا عَبْدُ الرَّحْمَنِ بْنُ أَبِي بَكْرَةَ عَنْ أَبِيهِ قَالَ كُنَّا عِنْدَ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَقَالَ أَلَا أُنَبِّئُكُمْ بِأَكْبَرِ الْكَبَائِرِ ثَلَاثًا الْإِشْرَاكُ بِاللَّهِ وَعُقُوقُ الْوَالِدَيْنِ وَشَهَادَةُ الزُّورِ أَوْ قَوْلُ الزُّورِ وَكَانَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ مُتَّكِئًا فَجَلَسَ فَمَا زَالَ يُكَرِّرُهَا حَتَّى قُلْنَا لَيْتَهُ سَكَتَ.

'Abdur-Rahman bin Abi Bakrah narrated that his father said: "We were with the Messenger of Allah (s.a.w) and he said: 'Shall I not tell you of the worst of major sins?' - (and the Prophet (s.a.w) repeated it) three times - 'Associating others with Allah, disobeying one's parents, and bearing false witness - or false speech.' The Messenger of Allah (s.a.w) was lying down, then he sat up and kept repeating it until we said: 'Would that he might fall silent."'
