Responsibility to give good treatment to our parents

Allah SWT said:

وَوَصَّيْنَا الْإِنْسٰنَ بِوٰلِدَيْهِ إِحْسٰنًا ۖ حَمَلَتْهُ أُمُّهُۥ كُرْهًا وَوَضَعَتْهُ كُرْهًا ۖ وَحَمْلُهُۥ وَفِصٰلُهُۥ ثَلٰثُونَ شَهْرًا ۚ حَتّٰىٓ إِذَا بَلَغَ أَشُدَّهُۥ وَبَلَغَ أَرْبَعِينَ سَنَةً قَالَ رَبِّ أَوْزِعْنِىٓ أَنْ أَشْكُرَ نِعْمَتَكَ الَّتِىٓ أَنْعَمْتَ عَلَىَّ وَعَلٰى وٰلِدَىَّ وَأَنْ أَعْمَلَ صٰلِحًا تَرْضٰىهُ وَأَصْلِحْ لِى فِى ذُرِّيَّتِىٓ ۖ إِنِّى تُبْتُ إِلَيْكَ وَإِنِّى مِنَ الْمُسْلِمِينَ

"And We have enjoined upon man, to his parents, good treatment. His mother carried him with hardship and gave birth to him with hardship, and his gestation and weaning [period] is thirty months. [He grows] until, when he reaches maturity and reaches [the age of] forty years, he says, My Lord, enable me to be grateful for Your favor which You have bestowed upon me and upon my parents and to work righteousness of which You will approve and make righteous for me my offspring. Indeed, I have repented to You, and indeed, I am of the Muslims."

(Quran, Surah Al-Ahqaf, 46: Verse 15)
