Overall meaning : I swear by the perfectly built and superbly designed heavens that you, Quraysh unbelievers, hold contradictory views and statements (by describing the Qur’an sometimes as magic, sometimes as poetry and at other times as fables of the ancients and by calling the Prophet sometimes a magician, sometimes a madman and at other times a poet, among other things)!
Those who will be turned away from the Qur’an, as a result of such contradictory false statements that are fabricated to refute the truth, are only the ones who are deprived of it and are destined to be turned away from it, according to Allah’s foreknowledge, due to their preferring misguidance over guidance and unbelief over true faith.
Expelled from Allah’s mercy are these liars who utter falsehood—who are steeped in ignorance and are heedless of and blind to the truth. They mockingly ask, ‘When will this day on which we will be judged come?’
It will be the day when they will be tormented and burned in the Fire. ‘Taste your torment and burning as punishment for your unbelief,’ they will be told. ‘This is the very torment that you mockingly demanded to be hastened in the life of the world!’
