Allaah Commands to have Tawheed
Allaah Ta’ala said
(۞ وَقَضَىٰ رَبُّكَ أَلَّا تَعۡبُدُوۤا۟ إِلَّاۤ إِیَّاهُ وَبِٱلۡوَ ٰلِدَیۡنِ إِحْسَانًا إِمَّا یَبۡلُغَنَّ عِندَكَ ٱلۡكِبَرَ أَحَدُهُمَاۤ أَوۡ كِلَاهُمَا فَلَا تَقُل لَّهُمَاۤ أُفࣲّ وَلَا تَنۡهَرۡهُمَا وَقُل لَّهُمَا قَوۡلࣰا كَرِیمࣰا)
And your Lord has decreed that you worship none but Him. And that you be dutiful to your parents. If one of them or both of them attain old age in your life, say not to them a word of disrespect, nor shout at them but address them in terms of honour.
[Surah Al-Isra’ 23]
