Read Ruku 520 of the Quran

إِذْ نَادَىٰهُ رَبُّهُۥ بِٱلْوَادِ ٱلْمُقَدَّسِ طُوًى ﴿١٦﴾

When his Lord called to him in the sacred valley of Tuwa,

ٱذْهَبْ إِلَىٰ فِرْعَوْنَ إِنَّهُۥ طَغَىٰ ﴿١٧﴾

"Go to Pharaoh. Indeed, he has transgressed.

فَقُلْ هَل لَّكَ إِلَىٰٓ أَن تَزَكَّىٰ ﴿١٨﴾

And say to him, 'Would you [be willing to] purify yourself

وَأَهْدِيَكَ إِلَىٰ رَبِّكَ فَتَخْشَىٰ ﴿١٩﴾

And let me guide you to your Lord so you would fear [Him]?'"

فَأَرَىٰهُ ٱلْـَٔايَةَ ٱلْكُبْرَىٰ ﴿٢٠﴾

And he showed him the greatest sign,

فَكَذَّبَ وَعَصَىٰ ﴿٢١﴾

But Pharaoh denied and disobeyed.

ثُمَّ أَدْبَرَ يَسْعَىٰ ﴿٢٢﴾

Then he turned his back, striving.

فَحَشَرَ فَنَادَىٰ ﴿٢٣﴾

And he gathered [his people] and called out

فَقَالَ أَنَا۠ رَبُّكُمُ ٱلْأَعْلَىٰ ﴿٢٤﴾

And said, "I am your most exalted lord."

فَأَخَذَهُ ٱللَّهُ نَكَالَ ٱلْـَٔاخِرَةِ وَٱلْأُولَىٰٓ ﴿٢٥﴾

So Allah seized him in exemplary punishment for the last and the first [transgression].

إِنَّ فِى ذَٰلِكَ لَعِبْرَةًۭ لِّمَن يَخْشَىٰٓ ﴿٢٦﴾

Indeed in that is a warning for whoever would fear [Allah].
