وَأَدْخِلْ يَدَكَ فِى جَيْبِكَ تَخْرُجْ بَيْضَآءَ مِنْ غَيْرِ سُوٓءٍۢ ۖ فِى تِسْعِ ءَايَٰتٍ إِلَىٰ فِرْعَوْنَ وَقَوْمِهِۦٓ ۚ إِنَّهُمْ كَانُوا۟ قَوْمًۭا فَٰسِقِينَ
And put thy hand into the bosom of thy robe, it will come forth white but unhurt. (This will be one) among nine tokens unto Pharaoh and his people Lo! they were ever evil-living folk.
