Why did Allah create us?

وَمَا خَلَقۡتُ ٱلۡجِنَّ وَٱلۡإِنسَ إِلَّا لِيَعۡبُدُونِ ﴿٥٦﴾ مَآ أُرِيدُ مِنۡهُم مِّن رِّزۡقٖ وَمَآ أُرِيدُ أَن يُطۡعِمُونِ ﴿٥٧﴾ إِنَّ ٱللَّهَ هُوَ ٱلرَّزَّاقُ ذُو ٱلۡقُوَّةِ ٱلۡمَتِينُ ﴿٥٨﴾

And I did not create the jinn and mankind except to worship Me. I do not want from them any provision, nor do I want them to feed Me. Indeed, it is Allāh who is the [continual] Provider, the firm possessor of strength.

ٱلَّذِي خَلَقَ ٱلۡمَوۡتَ وَٱلۡحَيَوٰةَ لِيَبۡلُوَكُمۡ أَيُّكُمۡ أَحۡسَنُ عَمَلٗاۚ وَهُوَ ٱلۡعَزِيزُ ٱلۡغَفُورُ ﴿٢﴾

[He] who created death and life to test you [as to] which of you is best in deed - and He is the Exalted in Might, the Forgiving -

أَفَحَسِبۡتُمۡ أَنَّمَا خَلَقۡنَٰكُمۡ عَبَثٗا وَأَنَّكُمۡ إِلَيۡنَا لَا تُرۡجَعُونَ ﴿١١٥﴾

Then did you think that We created you uselessly and that to Us you would not be returned?"
