عَنْ أَنَسِ بْنِ مَالِكٍ رَضِيَ اللَّهُ عَنْهُ قَالَ ذَكَرَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ الْكَبَائِرَ أَوْ سُئِلَ عَنِ الْكَبَائِرِ فَقَالَ الشِّرْكُ بِاللَّهِ عَزَّ وَجَلَّ وَقَتْلُ النَّفْسِ وَعُقُوقُ الْوَالِدَيْنِ وَقَالَ أَلَا أُنَبِّئُكُمْ بِأَكْبَرِ الْكَبَائِرِ قَالَ قَوْلُ الزُّورِ أَوْ قَالَ شَهَادَةُ الزُّورِ قَالَ شُعْبَةُ أَكْبَرُ ظَنِّي أَنَّهُ قَالَ شَهَادَةُ الزُّورِ
Sayyiduna Anas bin Malik (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) mentioned the major sins, or he was asked about them. He (peace and blessings be upon him) said: Associating partners with Allah, killing a soul, and disobeying parents. Then he (peace and blessings be upon him) said: Shall I not inform you of the greatest of sins? Then he said: It is false speech. Or he said: It is false testimony. Imam Shu’bah says: The predominant opinion is that he (peace and blessings be upon him) mentioned false testimony.
