When Allah sent Sayyiduna Musa to pharaoh for guiding him, Allah bestowed Sayyiduna Musa with two miracles, one of which was ‘the blessed staff’ and the other was the miracle of ‘the glowing hand’. When Sayyiduna Musa used to put his hand into the neck of his shirt, upon drawing it out, it would begin to glow! When he would place his blessed hand again in the neck of his shirt, it would restore its original condition. The Holy Quran has mentioned this miracle repeatedly in different Surahs. For example, it is mentioned in Surah Taahaa:
وَاضْمُمْ یَدَکَ اِلٰی جَنَاحِکَ تَخْرُجْ بَیۡضَآءَ مِنْ غَیۡرِ سُوۡٓءٍ اٰیَۃً اُخْرٰی ﴿ۙ22﴾لِنُرِیَکَ مِنْ اٰیٰتِنَا الْکُبْرٰی ﴿ۚ23﴾
And place your hand joining with your arm (below the armpit); it will come out (shining) bright white, not due to any illness; (this is) one more sign.’ ‘In order that We may show you Our great signs.
[Kanz-ul-Iman (Translation of Quran)J (Part 16, Surah Taahaa, Ayah 22-23)
This miracle is known as the glowing hand) and it is a unique and a wonderful miracle. Sayyiduna Ibn ‘Abbas has stated that during the day and night, Noor (light) would radiate from the sacred hand of Sayyiduna Musa as it radiates from the sun.
(Khaza ‘in-ul-‘Irfan, pp. 563; part 16, Surah Taahaa, Ayah 22)
