Surah Al-Qasas (The Stories), Verse 32

اُسْلُكْ یَدَكَ فِیْ جَیْبِكَ تَخْرُجْ بَیْضَآءَ مِنْ غَیْرِ سُوْٓءٍ وَّاضْمُمْ اِلَیْكَ جَنَاحَكَ مِنَ الرَّهْبِ فَذٰنِكَ بُرْهَانٰنِ مِنْ رَّبِّكَ اِلٰی فِرْعَوْنَ وَمَلَاۡىِٕهٖ اِنَّهُمْ كَانُوْا قَوْمًا فٰسِقِیْنَ ۟

“"Move thy hand into thy bosom, and it will come forth white without stain (or harm), and draw thy hand close to thy side (to guard) against fear. Those are the two credentials from thy Lord to Pharaoh and his Chiefs: for truly they are a people rebellious and wicked."”
