Compiled by Imam Muhammad al-Bukhari
حَدَّثَنِي مُحَمَّدُ بْنُ الْوَلِيدِ، حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ، حَدَّثَنَا شُعْبَةُ، قَالَ حَدَّثَنِي عُبَيْدُ اللَّهِ بْنُ أَبِي بَكْرٍ، قَالَ سَمِعْتُ أَنَسَ بْنَ مَالِكٍ ـ رضى الله عنه ـ قَالَ ذَكَرَ رَسُولُ اللَّهِ صلى الله عليه وسلم الْكَبَائِرَ، أَوْ سُئِلَ عَنِ الْكَبَائِرِ فَقَالَ " الشِّرْكُ بِاللَّهِ، وَقَتْلُ النَّفْسِ، وَعُقُوقُ الْوَالِدَيْنِ ". فَقَالَ " أَلاَ أُنَبِّئُكُمْ بِأَكْبَرِ الْكَبَائِرِ ـ قَالَ ـ قَوْلُ الزُّورِ ـ أَوْ قَالَ ـ شَهَادَةُ الزُّورِ ". قَالَ شُعْبَةُ وَأَكْثَرُ ظَنِّي أَنَّهُ قَالَ " شَهَادَةُ الزُّورِ ".
Allah's Messenger (ﷺ) mentioned the greatest sins or he was asked about the greatest sins. He said, "To join partners in worship with Allah; to kill a soul which Allah has forbidden to kill; and to be undutiful or unkind to one's parents." The Prophet (ﷺ) added, "Shall I inform you of the biggest of the great sins? That is the forged statement or the false witness." Shu`ba (the sub-narrator) states that most probably the Prophet said, "the false witness."
