Surat Al-Baqara (The Cow) - البقرة

وَمِنَ ٱلنَّاسِ مَن يُعْجِبُكَ قَوْلُهُۥ فِى ٱلْحَيَوٰةِ ٱلدُّنْيَا وَيُشْهِدُ ٱللَّهَ عَلَىٰ مَا فِى قَلْبِهِۦ وَهُوَ أَلَدُّ ٱلْخِصَامِ ﴿٢٠٤﴾

And among men is he whose speech about the life of this world causes you to wonder, and he calls on Allah to witness as to what is in his heart, yet he is the most violent of adversaries.
