﴿ فَجَعَلَهُمْ جُذَٰذًا إِلَّا كَبِيرًۭا لَّهُمْ لَعَلَّهُمْ إِلَيْهِ يَرْجِعُونَ ﴾

“And then he broke those [idols] to pieces, [all] save the biggest of them, so that they might [be able to] turn to it.”

When they went to their festival and they left Abraham behind in their township, he went to the house of their idols. (Then he reduced them to fragments) he destroyed them, (all save the chief of them) he left it intact, (that haply they might have recourse to it) after coming back from their festival and he could say that it was it that did it.
