وَلَقَدْ ءَاتَيْنَا مُوسَىٰ وَهَٰرُونَ ٱلْفُرْقَانَ وَضِيَآءً وَذِكْرًا لِّلْمُتَّقِينَ
2:54.
Commentary:
الفرقان (the Discrimination) may signify the signs and miracles which God gave to Moses, and ضیاء (Light) the arguments which proved the truth of his mission and ذکر (Remembrance) may signify the teaching itself.
The Torah has been called the Discrimination, a Light and a Remembrance. It was الفرقان (Discrimination) because in its own time it differentiated and discriminated between truth and falsehood. It was ضیاء (Light) in the sense that in its pristine purity it dispelled spiritual darkness and it was ذکر (Remembrance) as by acting upon its teaching the Israelites acquired great fame and eminence (ذکر meaning good reputation; eminence etc.)
