وَمِنَ ٱلنَّاسِ مَن يُعْجِبُكَ قَوْلُهُۥ فِى ٱلْحَيَوٰةِ ٱلدُّنْيَا وَيُشْهِدُ ٱللَّهَ عَلَىٰ مَا فِى قَلْبِهِۦ وَهُوَ أَلَدُّ ٱلْخِصَامِ
And of mankind there is he whoso conversation on the life of this world pleaseth thee (Muhammad), and he calleth Allah to witness as to that which is in his heart; yet he is the most rigid of opponents.
