Quran 63:1 from Surah Al-Munaafiqoon on Divine Marvels.
إِذَا جَآءَكَ ٱلۡمُنَٰفِقُونَ قَالُواْ نَشۡهَدُ إِنَّكَ لَرَسُولُ ٱللَّهِۗ وَٱللَّهُ يَعۡلَمُ إِنَّكَ لَرَسُولُهُۥ وَٱللَّهُ يَشۡهَدُ إِنَّ ٱلۡمُنَٰفِقِينَ لَكَٰذِبُونَ
English translation: When come to you the hypocrites they say We testify that you (are) surely (the) Messenger (of) Allah And Allah knows that you (are) surely His Messenger and Allah testifies that the hypocrites (are) surely liars
Transliteration: idha jaaka al-munafiquna qalu nashhadu innaka larasulu al-lahi wal-lahu ya'lamu innaka larasuluhu wal-lahu yashhadu inna al-munafiqina lakadhibuna
