An-Nazi'at 79:19

إِذْ نَادَاهُ رَبُّهُ بِالْوَادِ الْمُقَدَّسِ طُوًى

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

اذْهَبْ إِلَىٰ فِرْعَوْنَ إِنَّهُ طَغَىٰ

"Go to Pharaoh. Indeed, he has transgressed.

فَقُلْ هَل لَّكَ إِلَىٰ أَن تَزَكَّىٰ

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

فَأَرَاهُ الْآيَةَ الْكُبْرَىٰ

And he showed him the greatest sign,

فَكَذَّبَ وَعَصَىٰ

But Pharaoh denied and disobeyed.

ثُمَّ أَدْبَرَ يَسْعَىٰ

Then he turned his back, striving.
