Surah Al-An'am — Ayah 33 (6:33)
قَدۡ نَعۡلَمُ إِنَّهُۥ لَيَحۡزُنُكَ ٱلَّذِي يَقُولُونَۖ فَإِنَّهُمۡ لَا يُكَذِّبُونَكَ وَلَٰكِنَّ ٱلظَّٰلِمِينَ بِـَٔايَٰتِ ٱللَّهِ يَجۡحَدُونَ ٣٣
English translation (Saheeh International)
We know that you, [O Muḥammad], are saddened by what they say. And indeed, they do not call you untruthful, but it is the verses of Allāh that the wrongdoers reject.
Brief commentary
I know that their outer denial of you, O Messenger, upsets you. Know that inside they do not deny you, because they know your truthfulness and honesty. Instead, they are people who do wrong because of their rejection of Allah’s words and they therefore dislike what you have brought and deny it on the outside.
