قَالَ لَهُم مُّوسَىٰ وَيْلَكُمْ لَا تَفْتَرُوا عَلَى اللَّهِ كَذِبًا فَيُسْحِتَكُم بِعَذَابٍ ۖ وَقَدْ خَابَ مَنِ افْتَرَىٰ (61)
(20:61) (On the very occasion) Moses warned (his adversaries), saying, *33 "O unfortunate people, do not invent falsehoods in regard to Allah: *34 otherwise He will destroy you by a scourge: for whoso invented a falsehood, perished."
*33) The "adversaries" whom Prophet Moses addressed were Pharaoh and his courtiers who had dubbed him as a "sorcerer", and not the common people, who had yet to see the encounter between him and the magicians.
*34) "The falsehoods" were that they had dubbed Allah's Messenger as a "sorcerer" and his miracles as "a piece of sorcery".
