﴿ وَإِذَا تُتْلَىٰ عَلَيْهِمْ ءَايَٰتُنَا بَيِّنَٰتٍۢ تَعْرِفُ فِى وُجُوهِ ٱلَّذِينَ كَفَرُوا۟ ٱلْمُنكَرَ ۖ يَكَادُونَ يَسْطُونَ بِٱلَّذِينَ يَتْلُونَ عَلَيْهِمْ ءَايَٰتِنَا ۗ قُلْ أَفَأُنَبِّئُكُم بِشَرٍّۢ مِّن ذَٰلِكُمُ ۗ ٱلنَّارُ وَعَدَهَا ٱللَّهُ ٱلَّذِينَ كَفَرُوا۟ ۖ وَبِئْسَ ٱلْمَصِيرُ ﴾

“As it is, whenever Our messages are conveyed unto them in all their clarity, thou canst perceive utter repugnance on the faces of those who are bent on denying the truth: they would almost assault those who convey Our messages unto them! Say: “Shall I, then, tell you of something worse than what you feel at present? It is the fire [of the hereafter] that God has promised to those who are bent on denying the truth: and how vile a journey’s end!””

Inevitably, the call for pure monotheism is intolerable to those who have reposed their faith in many gods rather than in the one and only God. They become deeply agitated when their gods and beloved personalities are criticised. Being unable to refute by rational arguments the call of Truth, they resort to violence against the upholder of the call of monotheism, and want him to be eliminated altogether. When told by God that their behaviour is unwise in the extreme, they are not prepared to bear even verbal criticism. But what will be their condition subsequently when they will be required to undergo the punishment of Hellfire on account of their opposition to the Truth?
