He is Allah. There is no god ˹worthy of worship˺ except Him. All praise belongs to Him in this life and the next. All authority is His.And to Him you will ˹all˺ be returned.Quran 28:70 (Surah Al-Qasas, The Stories)
Surah al-Qasas [The Story] takes it name from being mentioned in [28:25], ‘Then one of the two women came to him walking with shyness. She said, “Indeed, my father invites you that he may reward you for having watered for us.” So when he came to him and related to him the story, he said, “Fear not. You have escaped from the wrongdoing people.”
This Surah has 88 Ayat.
وَهُوَ ٱللَّهُ
لَاۤ إِلَـٰهَ إِلَّا هُوَۖ 

لَهُ ٱلۡحَمۡدُ 
فِی ٱلۡأُولَىٰ وَٱلۡءَاخِرَةِۖ 

وَلَهُ ٱلۡحُكۡمُ 
وَإِلَیۡهِ تُرۡجَعُونَ
The basic theme of this Surah is the prophethood.
Some aspects of the life of Prophet Moses -peace be upon him- are mentioned to show the similarity between him and Prophet Muhammad – peace be upon all the prophets of Allah.
There are also answers here to the questions and doubts that were raised by some non-believers.
اور وہی خدا ہے 

اس کے سوا کوئی معبود نہیں

دنیا اور آخرت میں اُسی کی تعریف ہے 

اور اُسی کا حکم 
اور اسی کی طرف 
تم لوٹائے جاؤ گے
