وَمَكَرُوا۟ وَمَكَرَ ٱللَّهُ ۖ وَٱللَّهُ خَيْرُ ٱلْمَـٰكِرِينَ
Wa makaroo wa makaral laahu wallaahu khairul maakireen
They schemed, and God schemed — and God is the best of schemers.
Arabic repeats a single word on purpose here, answering the plotters with their own term; the rhetoricians call this mushākala, shaping the reply to match the wording of the challenge. Classical commentators handled the word carefully, reading makr said of God as the overturning of a plan, since deceit belongs to the plotters alone. What that overturning consisted of arrives in the next verse.
