﴿ وَٱضْمُمْ يَدَكَ إِلَىٰ جَنَاحِكَ تَخْرُجْ بَيْضَآءَ مِنْ غَيْرِ سُوٓءٍ ءَايَةً أُخْرَىٰ ﴾

“"Now place thy hand within thy armpit: it will come forth [shining] white, without blemish, as another sign [of Our grace],”

Clasp thy hand to thy side. It will come forth white without ugliness, as another sign. Moses had two miracles. One was outside of himself, namely the staff, and the other was within himself, namely the white hand. The staff was a sample of the signs of the horizons, and the white hand was a sample of the signs of the souls. The Lord of the Worlds built the road of tawḤīd on the recognition of these two. He says, “We shall show them Our signs on the horizons and in their souls until it is clear to them that He is the Real” [41:53].
