حَدَّثَنَا مُسَدَّدٌ ، حَدَّثَنَا بِشْرُ بْنُ الْمُفَضَّلِ ، حَدَّثَنَا الْجُرَيْرِيُّ ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ أَبِي بَكْرَةَ ، عَنْ أَبِيهِ ـ رضى الله عنه ـ قَالَ قَالَ النَّبِيُّ صلى الله عليه وسلم " أَلاَ أُنَبِّئُكُمْ بِأَكْبَرِ الْكَبَائِرِ ". ثَلاَثًا. قَالُوا بَلَى يَا رَسُولَ اللَّهِ. قَالَ " الإِشْرَاكُ بِاللَّهِ، وَعُقُوقُ الْوَالِدَيْنِ ". وَجَلَسَ وَكَانَ مُتَّكِئًا فَقَالَ " أَلاَ وَقَوْلُ الزُّورِ " . قَالَ فَمَا زَالَ يُكَرِّرُهَا حَتَّى قُلْنَا لَيْتَهُ سَكَتَ. وَقَالَ إِسْمَاعِيلُ بْنُ إِبْرَاهِيمَ حَدَّثَنَا الْجُرَيْرِيُّ حَدَّثَنَا عَبْدُ الرَّحْمَنِ .
The Prophet (ﷺ) said thrice, "Should I inform you out the greatest of the great sins?" They said, "Yes, O Allah's Messenger (ﷺ)!" He said, "To join others in worship with Allah and to be undutiful to one's parents." The Prophet (ﷺ) then sat up after he had been reclining (on a pillow) and said, "And I warn you against giving a false witness, and he kept on saying that warning till we thought he would not stop. (See Hadith No. 7, Vol. 8)
