﴿ إِنَّ ٱلَّذِينَ يَكْفُرُونَ بِٱللَّهِ وَرُسُلِهِۦ وَيُرِيدُونَ أَن يُفَرِّقُوا۟ بَيْنَ ٱللَّهِ وَرُسُلِهِۦ وَيَقُولُونَ نُؤْمِنُ بِبَعْضٍۢ وَنَكْفُرُ بِبَعْضٍۢ وَيُرِيدُونَ أَن يَتَّخِذُوا۟ بَيْنَ ذَٰلِكَ سَبِيلًا ﴾

“VERILY, those who deny God and His apostles by endeavouring to make a distinction between [belief in] God and [belief in] His apostles, and who say, "We believe in the one but we deny the other," and want to pursue a path in-between -”

Those who disbelieve in God and His messengers and seek to divide between God and His messengers by believing in Him but not in them and say ‘We believe in some of the messengers and disbelieve in some’ of the others and seek to adopt a way a path to follow between them between unbelief and belief.
