﴿ وَلَوْ دُخِلَتْ عَلَيْهِم مِّنْ أَقْطَارِهَا ثُمَّ سُئِلُوا۟ ٱلْفِتْنَةَ لَءَاتَوْهَا وَمَا تَلَبَّثُوا۟ بِهَآ إِلَّا يَسِيرًۭا ﴾

“Now if their town had been stormed, and they had been asked [by the enemy] to commit apos­tasy, [the hypocrites] would have done so without much delay”

And had they been invaded in it namely Medina from all sides and had they been exhorted in other words had the invaders exhorted them to treachery a return to idolatrous ways they would have committed it read la-ātawhā or la-atawhā meaning ‘they would have offered it’ or ‘they would have committed it’ respectively and would have hesitated thereupon but a little.
