Yes. Allah commands kindness to parents and forbids even saying “uff” to them (17:23). The Prophet ﷺ listed disobedience to parents among the greatest sins.
Und dein Herr hat bestimmt, daß ihr nur Ihm dienen und zu den Eltern gütig sein sollt. Wenn nun einer von ihnen oder beide bei dir ein hohes Alter erreichen, so sag nicht zu ihnen: "Pfui!" und fahre sie nicht an, sondern sag zu ihnen ehrerbietige Worte.
Und Wir haben dem Menschen seine Eltern anbefohlen - seine Mutter hat ihn unter wiederholter Schwäche getragen, und seine Entwöhnung (erfolgt) innerhalb von zwei Jahren -: "Sei Mir und deinen Eltern dankbar. Zu Mir ist der Ausgang."
Hadith
Sahih al-Bukhari 5976
Narrated Abu Bakra:Allah's Messenger (ﷺ) said thrice, "Shall I not inform you of the biggest of the great sins?" We said, "Yes, O Allah's Messenger (ﷺ)" He said, "To join partners in worship with Allah: to be undutiful to one's parents." The Prophet (ﷺ) sat up after he had been reclining and added, "And I warn you against giving forged statement and a false witness; I warn you against giving a forged statement and a false witness." The Prophet kept on saying that warning till we thought that he would not stop
Arabic text (with chain of narrators)
حَدَّثَنِي إِسْحَاقُ، حَدَّثَنَا خَالِدٌ الْوَاسِطِيُّ، عَنِ الْجُرَيْرِيِّ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ أَبِي بَكْرَةَ، عَنْ أَبِيهِ ـ رضى الله عنه ـ قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " أَلاَ أُنَبِّئُكُمْ بِأَكْبَرِ الْكَبَائِرِ ". قُلْنَا بَلَى يَا رَسُولَ اللَّهِ. قَالَ " الإِشْرَاكُ بِاللَّهِ، وَعُقُوقُ الْوَالِدَيْنِ ". وَكَانَ مُتَّكِئًا فَجَلَسَ فَقَالَ " أَلاَ وَقَوْلُ الزُّورِ وَشَهَادَةُ الزُّورِ، أَلاَ وَقَوْلُ الزُّورِ وَشَهَادَةُ الزُّورِ ". فَمَا زَالَ يَقُولُهَا حَتَّى قُلْتُ لاَ يَسْكُتُ.
