﴿ وَلَقَدْ ءَاتَيْنَا مُوسَىٰ وَهَٰرُونَ ٱلْفُرْقَانَ وَضِيَآءًۭ وَذِكْرًۭا لِّلْمُتَّقِينَ ﴾

“AND, INDEED, We vouchsafed unto Moses and Aaron [Our revelation as] the standard by which to discern the true from the false, and as a [guiding] light and a reminder for the God-conscious”

(And We verily gave Moses and Aaron the Criterion) the deliverer from dubious matters; it is also said that the Criterion means: victory and the upper hand over Pharaoh (and a light) which shows error (and a Reader) and an admonition (for those who keep from evil) for those who ward off idolatry, disbelief and indecencies.
