Saad • EN-TAFSIR-IBN-ABBAS
﴿ وَعَجِبُوٓا۟ أَن جَآءَهُم مُّنذِرٌۭ مِّنْهُمْ ۖ وَقَالَ ٱلْكَٰفِرُونَ هَٰذَا سَٰحِرٌۭ كَذَّابٌ ﴾
“Now these [people] deem it strange that a warner should have come unto them from their own midst - and [so] the deniers of the truth are saying: “A [mere] spellbinder is he, a liar!”
(And they) i.e. the Quraysh (marvel that a warner) a warning messenger (from among themselves) from their own lineage (hath come unto them, and the disbelievers) the disbelievers of Mecca (say: This) meaning Muhammad (pbuh) (is a wizard) who sows dispute between people, (a charlatan) who lies about Allah.
