Surah Taha — Ayah 104 (20:104)
نَّحۡنُ أَعۡلَمُ بِمَا يَقُولُونَ إِذۡ يَقُولُ أَمۡثَلُهُمۡ طَرِيقَةً إِن لَّبِثۡتُمۡ إِلَّا يَوۡمٗا ١٠٤
English translation (Saheeh International)
We are most knowing of what they say when the best of them in manner [i.e., wisdom or speech] will say, "You remained not but one day."
Brief commentary
I know best what they secretly say amongst themselves, with none of it escaping Me, when the most intelligent of them says: “You did not stay in the Transitory Stage except for one day, no more”.
