وَأَدْخِلْ يَدَكَ فِى جَيْبِكَ تَخْرُجْ بَيْضَآءَ مِنْ غَيْرِ سُوٓءٍۢ ۖ فِى تِسْعِ ءَايَـٰتٍ إِلَىٰ فِرْعَوْنَ وَقَوْمِهِۦٓ ۚ إِنَّهُمْ كَانُوا۟ قَوْمًۭا فَـٰسِقِينَ

And put your hand into the opening of your garment [at the breast]; it will come out white without disease. [These are] among the nine signs [you will take] to Pharaoh and his people. Indeed, they have been a people defiantly disobedient."

— An-Naml 27:12
