Qur'ān 63:1 · Al-Munafiqun (المنافقون)

بِسْمِ ٱللَّهِ ٱلرَّحْمَـٰنِ ٱلرَّحِيمِ إِذَا جَآءَكَ ٱلْمُنَـٰفِقُونَ قَالُوا۟ نَشْهَدُ إِنَّكَ لَرَسُولُ ٱللَّهِ ۗ وَٱللَّهُ يَعْلَمُ إِنَّكَ لَرَسُولُهُۥ وَٱللَّهُ يَشْهَدُ إِنَّ ٱلْمُنَـٰفِقِينَ لَكَـٰذِبُونَ

When the hypocrites come to you, [O Muhammad], they say, "We testify that you are the Messenger of Allah." And Allah knows that you are His Messenger, and Allah testifies that the hypocrites are liars.
