Surah Al-Munafiqun · 63:1

إِذَا جَاءَكَ الْمُنَافِقُونَ قَالُوا نَشْهَدُ إِنَّكَ لَرَسُولُ اللَّهِ ۗ وَاللَّهُ يَعْلَمُ إِنَّكَ لَرَسُولُهُ وَاللَّهُ يَشْهَدُ إِنَّ الْمُنَافِقِينَ لَكَاذِبُونَ

“When the hypocrites come to you [O Prophet], they say, "We bear witness that you are certainly the Messenger of Allah" — and surely Allah knows that you are His Messenger — but Allah bears witness that the hypocrites are truly liars”
