Quran 9, Al-Tawba (Repentance) ⓘ

9:44Those 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).

لَا يَسْتَأْذِنُكَ الَّذِينَ يُؤْمِنُونَ بِاللَّهِ وَالْيَوْمِ الْآخِرِ أَنْ يُجَاهِدُوا بِأَمْوَالِهِمْ وَأَنْفُسِهِمْ وَاللَّهُ عَلِيمٌ بِالْمُتَّقِينَ
