﴿ ذَٰلِكَ بِأَنَّهُمْ قَالُوا۟ لَن تَمَسَّنَا ٱلنَّارُ إِلَّآ أَيَّامًۭا مَّعْدُودَٰتٍۢ ۖ وَغَرَّهُمْ فِى دِينِهِم مَّا كَانُوا۟ يَفْتَرُونَ ﴾

“simply because they claim, "The fire will most certainly not touch us for more than a limited number of days": and thus the false beliefs which they invented have [in time] caused them to betray their faith.”

God’s guidance is one and the same as that revealed to various prophets from time to time in various languages. The same guidance was revealed to the Final Prophet in the form of the Quran. Due to this uniformity in content, recognizing the call of the Quran is not difficult for the People of the Book, i.e. believers in other revealed scriptures. The only difference between the Quranic call and former divine scriptures lies in the fact that the Quran has purified the religion of God of all human interpolations. Then why is it that many people deny the call of the Quran? It is because the Quranic call does not appear to them to be a serious matter, vis à vis their self-styled concepts by which they feel that they have safeguarded themselves from the fire of hell. It is as a result of this mindset that they think that, even if they do not recognize the truth, their salvation is still not at risk. But when the divine scales are put in place, they will realize how deluded they were in their wishful thinking.
