Regarding honoring one's parents
حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرِ بْنِ زِيَادٍ، وَقَالَ، أَخْبَرَنَا ح، وَحَدَّثَنَا عَبَّادُ بْنُ مُوسَى، قَالاَ حَدَّثَنَا إِبْرَاهِيمُ بْنُ سَعْدٍ، عَنْ أَبِيهِ، عَنْ حُمَيْدِ بْنِ عَبْدِ الرَّحْمَنِ، عَنْ عَبْدِ اللَّهِ بْنِ عَمْرٍو، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " إِنَّ مِنْ أَكْبَرِ الْكَبَائِرِ أَنْ يَلْعَنَ الرَّجُلُ وَالِدَيْهِ " . قِيلَ يَا رَسُولَ اللَّهِ كَيْفَ يَلْعَنُ الرَّجُلُ وَالِدَيْهِ قَالَ " يَلْعَنُ أَبَا الرَّجُلِ فَيَلْعَنُ أَبَاهُ وَيَلْعَنُ أُمَّهُ فَيَلْعَنُ أُمَّهُ " .
‘Abd Allah b. ‘Amr (b. al-As) reported the Messenger of Allah (May peace be upon him) as saying: A man’s reviling of his parents is one of the grave sins. He was asked : Messenger of Allah! How does a man revile his parents? He replied: He reviles the father of a man who then reviles his father, and he reviles a man’s mother and he reviles his.
