Surah 17. Al-Israa
Ayah 23 - 24
23 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
24 وَٱخْفِضْ لَهُمَا جَنَاحَ ٱلذُّلِّ مِنَ ٱلرَّحْمَةِ وَقُل رَّبِّ ٱرْحَمْهُمَا كَمَا رَبَّيَانِى صَغِيرًا
[23-24] Your Lord has enjoined the following:25
1. You should not worship anyone but Him.26
2. Treat your parents with great consideration; if either or both of them live with you in their old age, do not say even "fie" to them: nor rebuke them, but speak kind words to them; treat them with humility and tenderness and pray: "Lord, be merciful to them just as they brought me up with kindness and affection."
25In the succeeding verses, those main basic principles have been put forward on which Islam desires to build the whole structure of human life. These form, so to say, the Manifesto of the Invitation of the Holy Prophet declared by him at the end of the Makki stage of his mission, on the eve of the new stage at AI-Madinah so that it should be known to all that the new Islamic Society and State were going to be built on such and such ideological, moral, cultural economic and legal principles. (Please also refer to vv. 151-153 and E.N.'s thereof of Chapter VI).
26This commandment is very comprehensive. It prohibits not only the worship of anyone except Allah but also implies that one should obey and serve and submit to Allah alone without question: one should accept His Commandments and Law alone to be worthy of obedience and His authority to be supreme above all. This was not merely an instruction confined to a religious creed and individual practice but it served as the foundation of the moral, cultural, and political system which was practically established in Al-Madinah by the Holy Prophet. Its first and foremost principle was that Allah alone is the Master, Sovereign and Law-giver.
