1. Sanitized Theology:
The verse alters the original biblical sign in Exodus 4:6, where Moses's hand becomes "leprous like snow" as a demonstration of God's power over decay and healing. The Quran changes this to a hand "white without disease," sanitizing the miracle because the author likely viewed leprosy as too undignified for a prophet.
2. Miracle Reduced to Magic:
By stripping away the element of dreaded disease and sudden restoration, the Quran removes the theological depth of God's sovereignty over life and death. This turns an existentially powerful sign of divine authority into a superficial, glowing visual trick.
The Quran Verse
Surah 27:12:
And put your hand into the opening of your [robe]; it will come out white without disease...
The Biblical Contrast
Exodus 4:6:
...and when he took it out, behold, his hand was leprous like snow.
The Bible says God gave Moses a sign by making his hand leprous (a dreaded disease) and then healing it. The Quran repeatedly specifies "white without disease" (bayḍā'a min ghayri sū'in).
Critics argue this is a "theological correction" born of a misunderstanding.
The author of the Quran likely felt that a Prophet of God having a "disease" like leprosy was undignified, so the miracle was changed to a simple "light" or "whiteness." This alters the original biblical sign of God's power over life and decay into a mere magic trick.
