An-Nisa 4:143

Muthabthabeena bayna thalikala ila haola-i wala ilahaola-i waman yudlili Allahu falantajida lahu sabeela

Wavering between them, [belonging] neither to these [i.e., the believers] nor to those [i.e., the disbelievers]. And whoever Allāh sends astray - never will you find for him a way.

wavering between (this and) that, neither here nor there. Whomsoever Allah lets go astray, you shall never find a way for him.
