Disobedience to parents as a major sin

۞ قُلْ تَعَالَوْا۟ أَتْلُ مَا حَرَّمَ رَبُّكُمْ عَلَيْكُمْ ۖ أَلَّا تُشْرِكُوا۟ بِهِۦ شَيْـًۭٔا ۖ وَبِٱلْوَٰلِدَيْنِ إِحْسَٰنًۭا ۖ وَلَا تَقْتُلُوٓا۟ أَوْلَٰدَكُم مِّنْ إِمْلَٰقٍۢ ۖ نَّحْنُ نَرْزُقُكُمْ وَإِيَّاهُمْ ۖ وَلَا تَقْرَبُوا۟ ٱلْفَوَٰحِشَ مَا ظَهَرَ مِنْهَا وَمَا بَطَنَ ۖ وَلَا تَقْتُلُوا۟ ٱلنَّفْسَ ٱلَّتِى حَرَّمَ ٱللَّهُ إِلَّا بِٱلْحَقِّ ۚ ذَٰلِكُمْ وَصَّىٰكُم بِهِۦ لَعَلَّكُمْ تَعْقِلُونَ

Say: "Come, I will rehearse what Allah hath (really) prohibited you from": Join not anything as equal with Him; be good to your parents; kill not your children on a plea of want;- We provide sustenance for you and for them;- come not nigh to shameful deeds. Whether open or secret; take not life, which Allah hath made sacred, except by way of justice and law: thus doth He command you, that ye may learn wisdom.

۞ وَقَضَىٰ رَبُّكَ أَلَّا تَعْبُدُوٓا۟ إِلَّآ إِيَّاهُ وَبِٱلْوَٰلِدَيْنِ إِحْسَٰنًا ۚ إِمَّا يَبْلُغَنَّ عِندَكَ ٱلْكِبَرَ أَحَدُهُمَآ أَوْ كِلَاهُمَا فَلَا تَقُل لَّهُمَآ أُفٍّۢ وَلَا تَنْهَرْهُمَا وَقُل لَّهُمَا قَوْلًۭا كَرِيمًۭا

Thy Lord hath decreed that ye worship none but Him, and that ye be kind to parents. Whether one or both of them attain old age in thy life, say not to them a word of contempt, nor repel them, but address them in terms of honour.

وَٱلَّذِى قَالَ لِوَٰلِدَيْهِ أُفٍّۢ لَّكُمَآ أَتَعِدَانِنِىٓ أَنْ أُخْرَجَ وَقَدْ خَلَتِ ٱلْقُرُونُ مِن قَبْلِى وَهُمَا يَسْتَغِيثَانِ ٱللَّهَ وَيْلَكَ ءَامِنْ إِنَّ وَعْدَ ٱللَّهِ حَقٌّۭ فَيَقُولُ مَا هَٰذَآ إِلَّآ أَسَٰطِيرُ ٱلْأَوَّلِينَ

But (there is one) who says to his parents, "Fie on you! Do ye hold out the promise to me that I shall be raised up, even though generations have passed before me (without rising again)?" And they two seek Allah's aid, (and rebuke the son): "Woe to thee! Have faith! for the promise of Allah is true." But he says, "This is nothing but tales of the ancients!"
