Qur'an 63:1

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 unto thee (O Muhammad), they say: We bear witness that thou art indeed Allah's messenger. And Allah knoweth that thou art indeed His messenger, and Allah beareth witness that the hypocrites indeed are speaking falsely.
