This ayah names the idols of Nuh (AS)'s people (Wadd, Suwa, Yaghuth, Ya'uq, Nasr) -- the same idols that, per Ibn Ishaq and Sahih al-Bukhari's tafsir, Amr ibn Luhay reintroduced into Arabia at this event.
“Don't leave a single house of kafirs on earth.”
The post directly quotes Nuh (AS)'s prayer as preserved in this ayah (Q71:26) -- asking Allah not to leave a single disbeliever's household on earth.
