The Night Journey
۞ وَقَضَىٰ رَبُّكَ أَلَّا تَعْبُدُوٓا۟ إِلَّآ إِيَّاهُ وَبِٱلْوَٰلِدَيْنِ إِحْسَـٰنًا ۚ إِمَّا يَبْلُغَنَّ عِندَكَ ٱلْكِبَرَ أَحَدُهُمَآ أَوْ كِلَاهُمَا فَلَا تَقُل لَّهُمَآ أُفٍّ وَلَا تَنْهَرْهُمَا وَقُل لَّهُمَا قَوْلًا كَرِيمًا
And your Lord has decreed that you not worship except Him, and to parents, good treatment. Whether one or both of them reach old age [while] with you, say not to them [so much as], "uff," and do not repel them but speak to them a noble word.

ٱنظُرْ كَيْفَ فَضَّلْنَا بَعْضَهُمْ عَلَىٰ بَعْضٍ ۚ وَلَلْـَٔاخِرَةُ أَكْبَرُ دَرَجَـٰتٍ وَأَكْبَرُ تَفْضِيلًا
Look how We have favored [in provision] some of them over others. But the Hereafter is greater in degrees [of difference] and greater in distinction.
لَّا تَجْعَلْ مَعَ ٱللَّهِ إِلَـٰهًا ءَاخَرَ فَتَقْعُدَ مَذْمُومًا مَّخْذُولًا
Do not make [as equal] with Allah another deity and [thereby] become censured and forsaken.
وَٱخْفِضْ لَهُمَا جَنَاحَ ٱلذُّلِّ مِنَ ٱلرَّحْمَةِ وَقُل رَّبِّ ٱرْحَمْهُمَا كَمَا رَبَّيَانِى صَغِيرًا
And lower to them the wing of humility out of mercy and say, "My Lord, have mercy upon them as they brought me up [when I was] small."
رَّبُّكُمْ أَعْلَمُ بِمَا فِى نُفُوسِكُمْ ۚ إِن تَكُونُوا۟ صَـٰلِحِينَ فَإِنَّهُۥ كَانَ لِلْأَوَّٰبِينَ غَفُورًا
Your Lord is most knowing of what is within yourselves. If you should be righteous [in intention] - then indeed He is ever, to the often returning [to Him], Forgiving.
