(An-Naml) 27 : 12
وَأَدْخِلْ يَدَكَ فِي جَيْبِكَ تَخْرُجْ بَيْضَاءَ مِنْ غَيْرِ سُوءٍ ۖ فِي تِسْعِ آيَاتٍ إِلَىٰ فِرْعَوْنَ وَقَوْمِهِ ۚ إِنَّهُمْ كَانُوا قَوْمًا فَاسِقِينَ
“And put your hand into your pocket; it will come out white without any evil; one among the 9 Signs to Pharaoh and his people, indeed they have become transgressed people".
See explanation 7: 133; 17: 101 and 26: 33.
