Sahih Muslim 87
Sahih Muslim · Book 1: The Book of Faith · The major sins and the most serious of them
It is narrated on the authority of 'Abdur-Rahman b. Abu Bakra that his father said:
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 صلى الله عليه وسلم فَقَالَ " أَلاَ أُنَبِّئُكُمْ بِأَكْبَرِ الْكَبَائِرِ - ثَلاَثًا - الإِشْرَاكُ بِاللَّهِ وَعُقُوقُ الْوَالِدَيْنِ وَشَهَادَةُ الزُّورِ أَوْ قَوْلُ الزُّورِ " . وَكَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم مُتَّكِئًا فَجَلَسَ فَمَازَالَ يُكَرِّرُهَا حَتَّى قُلْنَا لَيْتَهُ سَكَتَ .
We were in the company of the Messenger of Allah (ﷺ) that he observed: Should I not inform you about the most grievous of the grave sins? (The Holy Prophet) repeated it three times, and then said: Associating anyone with Allah, disobedience to parents, false testimony or false utterance. The Prophet was reclining, then he sat up, and he repeated it so many times that we wished that he should become silent.
