Surah Ash-Shu'ara — Ayah 31

قَالَ لَئِنِ ٱتَّخَذْتَ إِلَـٰهًا غَيْرِى لَأَجْعَلَنَّكَ مِنَ ٱلْمَسْجُونِينَ

[Pharaoh] said, "If you take a god other than me, I will surely place you among those imprisoned."

قَالَ أَوَلَوْ جِئْتُكَ بِشَىْءٍۢ مُّبِينٍۢ

[Moses] said, "Even if I brought you proof manifest?"

فَأَلْقَىٰ عَصَاهُ فَإِذَا هِىَ ثُعْبَانٌۭ مُّبِينٌۭ

So [Moses] threw his staff, and suddenly it was a serpent manifest.

وَنَزَعَ يَدَهُۥ فَإِذَا هِىَ بَيْضَآءُ لِلنَّـٰظِرِينَ

And he drew out his hand; thereupon it was white for the observers.
