Quran 9:44 At-Tawbah, ayah 44 of 129

لَا يَسْتَـْٔذِنُكَ ٱلَّذِينَ يُؤْمِنُونَ بِٱللَّهِ وَٱلْيَوْمِ ٱلْـَٔاخِرِ أَن يُجَـٰهِدُوا۟ بِأَمْوَٰلِهِمْ وَأَنفُسِهِمْ ۗ وَٱللَّهُ عَلِيمٌۢ بِٱلْمُتَّقِينَ ۝٤٤

9:44 Those who believe in Allah and the Last Day ask no leave of thee lest they should strive with their wealth and their lives. Allah is Aware of those who keep their duty (unto Him).
