Surah Al-A'raf — Ayah 108 (7:108)
وَنَزَعَ يَدَهُۥ فَإِذَا هِيَ بَيۡضَآءُ لِلنَّٰظِرِينَ ١٠٨
English translation (Saheeh International)
And he drew out his hand; thereupon it was white [with radiance] for the observers.
Brief commentary
Then he drew out his hand from his shirt, near to his chest or under his arm, and it appeared completely white, not because of illness, but radiating brilliantly to all who saw it because of its extreme whiteness.
