And the answer of his [i.e., Abraham's] people was not but that they said, "Kill him or burn him," but Allāh saved him from the fire. Indeed in that are signs for a people who believe.
The only answer Abraham’s people gave to him - after he had instructed them to worship Allah alone and to give up the worship of idols - was that they said: Kill him or throw him into the fire in defence of your gods. But Allah saved him from the Fire. In his being saved from the fire after having been thrown into it there truly are lessons for people who have faith, because they are the one who benefit from such lessons.
