That verse—25:60 of al-Furqan—is an informative statement coupled with censure of those who were commanded to prostrate but refused; it is certainly not a commendation.
The same applies to the prostration passage in Surah an-Naml:
“I found her and her people prostrating to the sun instead of Allah. Satan has made their deeds appear attractive, so he has turned them away from the Path and they are not guided—so that they do not prostrate to Allah, the One who brings forth what is hidden in the heavens and the earth and knows whatever you conceal and whatever you declare. Allah—there is no deity but Him, Lord of the Mighty Throne” (an-Naml 27:24-26).
This, too, is a narrative that rebukes those who prostrate to other than Allah and fail to prostrate to Him. However, whoever recites it as “Alā, yā usjudū” (“Come, prostrate!”) treats it as an imperative command.
