9:45
إِنَّمَا يَسْتَـْٔذِنُكَ ٱلَّذِينَ لَا يُؤْمِنُونَ بِٱللَّهِ وَٱلْيَوْمِ ٱلْـَٔاخِرِ وَٱرْتَابَتْ قُلُوبُهُمْ فَهُمْ فِى رَيْبِهِمْ يَتَرَدَّدُونَ
9:45
It is only those who believe not in Allah and the Last Day and whose hearts are in doubt that ask your leave (to be exempted from Jihad). So in their doubts they waver. - Muhammad Taqi-ud-Din al-Hilali and Muhammad Muhsin Khan (English)
