28:32
ٱسْلُكْ يَدَكَ فِى جَيْبِكَ تَخْرُجْ بَيْضَآءَ مِنْ غَيْرِ سُوٓءٍ وَٱضْمُمْ إِلَيْكَ جَنَاحَكَ مِنَ ٱلرَّهْبِ ۖ فَذَٰنِكَ بُرْهَـٰنَانِ مِن رَّبِّكَ إِلَىٰ فِرْعَوْنَ وَمَلَإِي۟هِۦٓ ۚ إِنَّهُمْ كَانُوا۟ قَوْمًا فَـٰسِقِينَ
Insert your hand into the opening of your garment; it will come out white, without disease. And draw in your arm close to you [as prevention] from fear, for those are two proofs from your Lord to Pharaoh and his establishment. Indeed, they have been a people defiantly disobedient."
