Surah Ghafir, Ayah 5

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.

فَلاَ يَغْرُرْكَ تَقَلُّبُهُمْ فِى الْبِلاَدِ

(So let not their ability of going about here and there through the land deceive you!) means, their wealth and luxurious life. This is like the Ayah:

لاَ يَغُرَّنَّكَ تَقَلُّبُ الَّذِينَ كَفَرُواْ فِى الْبِلَـدِ - مَتَـعٌ قَلِيلٌ ثُمَّ مَأْوَاهُمْ جَهَنَّمُ وَبِئْسَ الْمِهَادُ

(Let not the free disposal (and affluence) of the disbelievers throughout the land deceive you. A brief enjoyment; then, their ultimate abode is Hell; and worst indeed is that place for rest.) (3:196-197)

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)

The appellations, the Almighty and All Knowing (al-‘Aziz and al-‘Alim), have been used here by way of argument in support of the Quran. At the time the Quran was revealed, this was in the nature of a forecast. Today it is an established fact. The Quran was revealed before the age of science and in the most unfavourable of circumstances. But, exactly according to its claim, it won over its opponents. The polytheists of Arabia, the Jews and the great Roman and Iranian empires–all were its enemies. But, in a very short period, it overcame all of them. This is an event which amply proves that the Quran had been sent by the All-Powerful and Supreme God. The other quality of the Quran is that it is a book based on facts. Even after the passage of fifteen hundred years, no statement of the Quran has been found to be at variance with the discoveries of science. This is proof of the fact that the Being who revealed it is All Knowing and All Aware. No matter relating either to heaven or earth is hidden from Him. He is uniformly aware of the past, present and future. This is the very Almighty God who is truly worthy of worship by man. It befits His Power and Knowledge that He should gather all human beings and take stock of their deeds, and then decide everyone’s fate with perfect justice, pardon those who turned towards Him and punish for their misdeeds those who rebelled against Him.
