فَمَا كَانَ جَوَابَ قَوْمِهِۦٓ إِلَّآ أَن قَالُوا۟ ٱقْتُلُوهُ أَوْ حَرِّقُوهُ فَأَنجَىٰهُ ٱللَّهُ مِنَ ٱلنَّارِ ۚ إِنَّ فِى ذَٰلِكَ لَـَٔايَـٰتٍ لِّقَوْمٍ يُؤْمِنُونَ Qur’an Al-Ankabut (29:24)Fama kana jawaba qawmihi illa an qaloo oqtuloohu aw harriqoohu faanjahu Allahu mina alnnari inna fee thalika laayatin liqawmin yuminoona
Lit., "the answer of his people was nothing but that they said" - thus connecting with the passage ending with verse {18}.
See note [64] on 21:69 .
The idolaters tried to burn Abraham because he smashed their idols. See 21:51-71 for the full story.
See xxi. 66-70. Abraham was cast into the fire, but he was unhurt, by the grace of Allah. So righteous people suffer no harm from the plots of the wicked. But they must leave the environment of evil even if they have to forsake their ancestral home, as Abraham did.
