One of the Attributes of the Disbelievers is That they dispute theAyat of Allah -- and The Consequences of that Allah tells us that noone rejects or disputes His signs after clear proof has come,

إِلاَّ الَّذِينَ كَفَرُواْ

(but those who disbelieve), i.e., those who reject the signs of Allah and His proof and evidence.

In verse 4, it was said: مَا يُجَادِلُ فِي آيَاتِ اللَّـهِ إِلَّا الَّذِينَ كَفَرُ‌وا (No one quarrels about the verses of Allah, except those who disbelieve.). This verse declares quarreling in the matter of the Qur'an an act of kufr (disbelief). And the Holy Prophet ﷺ has said: اِنَّ جِدَالأ فِی القُراٰنِ کُفرُ (Surely, quarreling (jidal) in the Qur'an is kufr.' (Reported by al-Baghawi, al-Baihaqi in ash-Shu'ab from Sayyidna Abu Hurairah ؓ ; and reported by Abu Dawud and al-Hakim who has rated it as 'Sahib- Mazhari)

It appears in Hadith that, on a certain day, the Holy Prophet ﷺ heard two persons quarreling about some verse of the Qur'an. He got angry, and came out with his blessed face showing the signs of anger. He said, 'communities before you were ruined because they had started quarreling in the matter of the Book of Allah.' (Reported by Muslim from ` Abdullah Ibn ` Amr Ibn Shu'aib - Mazhari)
