The Competition, Musa's Victory, and the Magician's Faith

Allah, the Exalted, informs about the magicians when they met Musa, that they said to Musa,

إِمَّآ أَن تُلْقِىَ

وَأَلْقِ مَا فِي يَمِينِكَ (And throw what is in your right hand - 20:69). Allah commanded Sayyidna Musa (علیہ السلام) by means of a revelation (وحی) to cast down what he held in his right hand, and when he threw down his staff it turned into a huge snake and ate up all the imaginary snakes which the Egyptian magicians had produced by their magic.
