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.  

كُنَّا عِنْدَ رَسُولِ اللَّهِ ﷺ فَقَالَ أَلاَ أُنَبِّئُكُمْ بِأَكْبَرِ الْكَبَائِرِ ثَلاَثًا الإِشْرَاكُ بِاللَّهِ وَعُقُوقُ الْوَالِدَيْنِ وَشَهَادَةُ الزُّورِ أَوْ قَوْلُ الزُّورِ وَكَانَ رَسُولُ اللَّهِ ﷺ مُتَّكِئًا فَجَلَسَ فَمَازَالَ يُكَرِّرُهَا حَتَّى قُلْنَا لَيْتَهُ سَكَتَ  

Associating anyone with Allah, disobedience to parents, killing a person and false utterance.  

عَنِ النَّبِيِّ ﷺ فِي الْكَبَائِرِ قَالَ الشِّرْكُ بِاللَّهِ وَعُقُوقُ الْوَالِدَيْنِ وَقَتْلُ النَّفْسِ وَقَوْلُ الزُّورِ  

I heard Anas b. Malik saying: The Messenger of Allah ﷺ talked about the major sins, or he was asked about the major sins. Upon this he observed: Associating anyone with Allah, killing of a person, disobedience to parents. He (the Prophet further) said: Should I not inform you about the gravest of the major sins, and (in this connection) observed: False utterance or false testimony. Shu'ba said. It was most probably" false testimony".  

ذَكَرَ رَسُولُ اللَّهِ ﷺ الْكَبَائِرَ أَوْ سُئِلَ عَنِ الْكَبَائِرِ فَقَالَ الشِّرْكُ بِاللَّهِ وَقَتْلُ النَّفْسِ وَعُقُوقُ الْوَالِدَيْنِ وَقَالَ أَلاَ أُنَبِّئُكُمْ بِأَكْبَرِ الْكَبَائِرِ قَالَ قَوْلُ الزُّورِ أَوْ قَالَ شَهَادَةُ الزُّورِ قَالَ شُعْبَةُ وَأَكْبَرُ ظَنِّي أَنَّهُ شَهَادَةُ الزُّورِ  

Avoid the seven noxious things. It was said (by the hearers): What are they, Messenger of Allah? He (the Holy Prophet) replied: Associating anything with Allah, magic, killing of one whom God has declared inviolate without a just cause, consuming the property of an orphan, and consuming of usury, turning back when the army advances, and slandering chaste women who are believers, but unwary.  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ اجْتَنِبُوا السَّبْعَ الْمُوبِقَاتِ قِيلَ يَا رَسُولَ اللَّهِ وَمَا هُنَّ قَالَ الشِّرْكُ بِاللَّهِ وَالسِّحْرُ وَقَتْلُ النَّفْسِ الَّتِي حَرَّمَ اللَّهُ إِلاَّ بِالْحَقِّ وَأَكْلُ مَالِ الْيَتِيمِ وَأَكْلُ الرِّبَا وَالتَّوَلِّي يَوْمَ الزَّحْفِ وَقَذْفُ الْمُحْصَنَاتِ الْغَافِلاَتِ الْمُؤْمِنَاتِ  

Abusing one's parents is one of the major sins. They (the hearers) said: Messenger of Allah, does a man abuse his parents too? He (the Holy Prophet) replied: Yes, one abuses the father of another man, who in turn abuses his father. One abuses his mother and he in turn abuses his (the former's) mother.  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ مِنَ الْكَبَائِرِ شَتْمُ الرَّجُلِ وَالِدَيْهِ قَالُوا يَا رَسُولَ اللَّهِ هَلْ يَشْتِمُ الرَّجُلُ وَالِدَيْهِ قَالَ نَعَمْ يَسُبُّ أَبَا الرَّجُلِ فَيَسُبُّ أَبَاهُ وَيَسُبُّ أُمَّهُ فَيَسُبُّ أُمَّهُ  

This hadith has also been transmitted on the authority of Sa'd b. Ibrahim with this chain of narrators.
