Is Magic or Saher word given in Quran is used by people when they failed to understand the message or Ayat of Allah and they thought it as an attempt to mislead them?

وَإِذۡ قَالَ عِيسَى ٱبۡنُ مَرۡيَمَ يَٰبَنِيٓ إِسۡرَٰٓءِيلَ إِنِّي رَسُولُ ٱللَّهِ إِلَيۡكُم مُّصَدِّقٗا لِّمَا بَيۡنَ يَدَيَّ مِنَ ٱلتَّوۡرَىٰةِ وَمُبَشِّرَۢا بِرَسُولٖ يَأۡتِي مِنۢ بَعۡدِي ٱسۡمُهُۥٓ أَحۡمَدُۖ فَلَمَّا جَآءَهُم بِٱلۡبَيِّنَٰتِ قَالُواْ هَٰذَا سِحۡرٞ مُّبِينٞ ٦

And call to mind when Jesus, son of Mary, said: “O Children of Israel, I am Allah's Messenger to you, I verify the Torah which has come before me, and I give you the glad tiding of a Messenger who shall come after me, his name being Ahmad.” Yet when he came to them with Clear Signs they said: “This is sheer trickery.”

Aur yaad karo Isa ibn-e-Maryam ki woh baat jo usne kahi thi ke “Aey bani Israel, main tumhari taraf Allah ka bheja hua Rasool hoon, Tasdeeq (verify/confirm) karne wala hoon us Taurat ki jo mujhse pehle aayi hui maujood hai, aur basharat (khushkhabri) dene wala hoon ek rasool ki jo mere baad aayega jiska naam Ahmed hoga. Magar jab woh unke paas khuli khuli nishaniyan lekar aaya to unhon ne kaha yeh to sareeh dhoka hai
