Abu Bakrah radiyallahu anhu relates that, "Rasoolullah sallallahu alaihe
wasallam once said, :
Must I show you a great sin, from among the greatest sins?" The sahaabah
replied, "Yes O Rasoolullah sallallahu alaihe wasallam, do tell us." Rasoolullah
sallallahu alaihe wasallam replied, "To ascribe a partner unto Allah. To disobey
one's parents. To bare false witness, (or tell a lie). (The narrator is not sure
which of the two Sayyidina Rasoolullah sallallahu alaihe wasallam had said). At
that time Rasoolullah sallallahu alaihe wasallam was leaning on something. When
he mentioned lies, he sat up, and because of its importance began to repeat it
many times, till we began hoping that he would stop, and not repeat it so many
times".
حَدَّثَنَا حُمَيْدُ بْنُ مَسْعَدَةَ، قَالَ: حَدَّثَنَا بِشْرُ بْنُ الْمُفَضَّلِ،
قَالَ: حَدَّثَنَا الْجُرَيْرِيُّ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ أَبِي بَكْرَةَ،
عَنْ أَبِيهِ، قَالَ: قَالَ رَسُولُ اللهِ صلى الله عليه وسلم: أَلا
أُحَدِّثُكُمْ بِأَكْبَرِ الْكَبَائِرِ؟ قَالُوا: بَلَى يَا رَسُولَ اللهِ قَالَ:
الإِشْرَاكُ بِاللَّهِ، وَعُقُوقُ الْوَالِدَيْنِ قَالَ: وَجَلَسَ رَسُولُ اللهِ
صلى الله عليه وسلم، وَكَانَ مُتَّكِئًا، قَالَ: وَشَهَادَةُ الزُّورِ، أَوْ
قَوْلُ الزُّورِ، قَالَ: فَمَا زَالَ رَسُولُ اللهِ صلى الله عليه وسلم،
يَقُولُهَا حَتَّى قُلْنَا: لَيْتَهُ سَكَتَ.
