At Tawbah Ayah 44

لَا يَسْتَــْٔذِنُكَ ٱلَّذِينَ يُؤْمِنُونَ بِٱللَّهِ وَٱلْيَوْمِ ٱلْأَخِرِ أَن يُجَـٰهِدُواْ بِأَمْوَٲلِهِمْ وَأَنفُسِهِمْ‌ۗ وَٱللَّهُ عَلِيمُۢ بِٱلْمُتَّقِينَ ٤٤ Those who believe in Allah and the Last Day do not ask for exemption from striving with their wealth and their lives. And Allah has perfect knowledge of those who are mindful ?of Him?.
