Surah 2 : Ayah 204

وَمِنَ ٱلنَّاسِ مَن يُعْجِبُكَ قَوْلُهُۥ فِى ٱلْحَيَوٰةِ ٱلدُّنْيَا وَيُشْهِدُ ٱللَّهَ عَلَىٰ مَا فِى قَلْبِهِۦ وَهُوَ أَلَدُّ ٱلْخِصَامِ

There are some [hypocrites] who amaze you with their words in the life of this world and call upon Allah to witness what is in their heart, yet they are the fiercest opponents[103].
