﴿ مُّذَبْذَبِينَ بَيْنَ ذَٰلِكَ لَآ إِلَىٰ هَٰٓؤُلَآءِ وَلَآ إِلَىٰ هَٰٓؤُلَآءِ ۚ وَمَن يُضْلِلِ ٱللَّهُ فَلَن تَجِدَ لَهُۥ سَبِيلًۭا ﴾

“wavering be­tween this and that, [true] neither to these nor those. But for him whom God lets go astray thou canst never find any way.”

Wavering hesitant all the time between that unbelief and belief — not belonging to these disbelievers neither to those believers; and he whom God sends astray you will never find for him a way a path back to guidance.
