They alone ask leave of you to stay behind who do not believe in God and the Last Day and whose hearts are doubtful uncertain about religion so in their doubt they waver they are confused.
- 9:4545
إِنَّمَا يَسْتَأْذِنُكَ الَّذِينَ لَا يُؤْمِنُونَ بِاللَّهِ وَالْيَوْمِ الْآخِرِ وَارْتَابَتْ قُلُوبُهُمْ فَهُمْ فِي رَيْبِهِمْ يَتَرَدَّدُونَ
Only they ask (for leave) who do not believe in God and the Last Day, whose hearts are full of doubt; and doubting they waver (between gain and loss).
