Argumentativeness

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

And of the people is he whose speech pleases you in worldly life, and he calls Allāh to witness as to what is in his heart, yet he is the fiercest of opponents.

وَلَقَدْ صَرَّفْنَا فِى هَـٰذَا ٱلْقُرْءَانِ لِلنَّاسِ مِن كُلِّ مَثَلٍ ۚ وَكَانَ ٱلْإِنسَـٰنُ أَكْثَرَ شَىْءٍ جَدَلًا

And We have certainly diversified in this Qur’ān for the people from every [kind of] example; but man has ever been, most of anything, [prone to] dispute.

أَوَلَمْ يَرَ ٱلْإِنسَـٰنُ أَنَّا خَلَقْنَـٰهُ مِن نُّطْفَةٍ فَإِذَا هُوَ خَصِيمٌ مُّبِينٌ

Does man not consider that We created him from a [mere] sperm-drop - then at once he is a clear adversary?
