Quran 63, Al-Munafiqun (The Hypocrites) ⓘ

63:1When 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.

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