Surah Taha — Ayah 61 (20:61)
قَالَ لَهُم مُّوسَىٰ وَيۡلَكُمۡ لَا تَفۡتَرُواْ عَلَى ٱللَّهِ كَذِبٗا فَيُسۡحِتَكُم بِعَذَابٖۖ وَقَدۡ خَابَ مَنِ ٱفۡتَرَىٰ ٦١
English translation (Saheeh International)
Moses said to them [i.e., the magicians summoned by Pharaoh], "Woe to you! Do not invent a lie against Allāh or He will exterminate you with a punishment; and he has failed who invents [such falsehood]."
Brief commentary
Moses said advising Pharaoh’s magicians: Beware, do not invent lies against Allah through the magic by means of which you deceive people, or He will eliminate you with a punishment from Him. Whoever invents lies against Allah is a loser.
