اِذَا جَآءَكَ الْمُنٰفِقُوْنَ قَالُوْا نَشْهَدُ اِنَّكَ لَرَسُوْلُ اللّٰهِ ۘ— وَاللّٰهُ یَعْلَمُ اِنَّكَ لَرَسُوْلُهٗ ؕ— وَاللّٰهُ یَشْهَدُ اِنَّ الْمُنٰفِقِیْنَ لَكٰذِبُوْنَ ۟ۚاِذَا جَآءَكَ الۡمُنٰفِقُوۡنَ قَالُوۡا نَشۡهَدُ اِنَّكَ لَرَسُوۡلُ اللّٰهِ ۘ وَاللّٰهُ يَعۡلَمُ اِنَّكَ لَرَسُوۡلُهٗ ؕ وَاللّٰهُ يَشۡهَدُ اِنَّ الۡمُنٰفِقِيۡنَ لَـكٰذِبُوۡنَ
When the hypocrites come to you, they say, ‘We bear witness that you are indeed the Messenger of God.’ God knows that you are indeed His Messenger, but God bears witness that the hypocrites are surely liars —
— Tazkirul Quran (En)
Tafseer of 63:1
It is a sign of hypocrisy in an individual if he indulges in tall talk and resorts to swearing oaths to reassure others of the truth of his words. A sincere man is subdued out of fear of God. He speaks more from his heart than from his tongue. A hypocrite is eager for men to hear his voice, while a sincere man is eager for God to hear his voice.
