The Disbelievers' Refrain from Faith means that They were simply awaiting Punishment

Threatening the idolators for their persistence in falsehood and their conceited delusions about this world, Allah says: Are these people waiting only for the angels to come and take their souls Qatadah said:

أَوْ يَأْتِىَ أَمْرُ رَبِّكَ

Commentary

It will be recalled that, after describing the blessings of Allah and proving that He was unique in the creation of the universe, the text made a pointed reference to how the polytheists chose to stick to their own ways of error. In the present verses, the text describes how they, not content with their own straying, tried that others should also go astray like them. The punishment they would get for doing that has also been stated here. Earlier to that (24), there is a question about the Qur’ an, and the addressees of the question, at this place, are the polytheists. It is their haughty and ignorant answer which has been mentioned here along with a warning of consequences for this attitude. Then, after five verses (30), the same question has been addressed to believers who fear Allah which is followed by their answer, and where a promise of reward for it has been mentioned.
