Hadith 16:24
'Abdullah bin 'Amro bin al-As (RAA) narrated that the Messenger of Allah (ﷺ) said:
“For a man to insult his parents, is one of the major sins.” It was asked, ‘Does a man insult his parents?’ He replied “Yes, he insults the father of a man who in return insults his father, and he insults a man’s mother who in return insult his.” Agreed upon.
وَعَنْ عَبْدِ اَللَّهِ بْنِ عَمْرِو بْنِ الْعَاصِ -رَضِيَ اَللَّهُ عَنْهُمَا- أَنَّ رَسُولَ اَللَّهِ - صلى الله عليه وسلم -قَالَ: { مِنْ اَلْكَبَائِرِ شَتْمُ اَلرَّجُلِ وَالِدَيْهِ. قِيلَ: وَهَلْ يَسُبُّ اَلرَّجُلُ وَالِدَيْهِ? قَالَ: نَعَمْ. يَسُبُّ أَبَا اَلرَّجُلِ, فَيَسُبُّ أَبَاهُ, وَيَسُبُّ أُمَّهُ, فَيَسُبُّ أُمَّهُ } مُتَّفَقٌ عَلَيْهِ
