Qur'an 63:1

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

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