Tafsir of Surah At-Tawba 9:44
﴿لَا يَسْتَأْذِنُكَ الَّذِينَ يُؤْمِنُونَ بِاللَّهِ وَالْيَوْمِ الْآخِرِ أَن يُجَاهِدُوا بِأَمْوَالِهِمْ وَأَنفُسِهِمْ وَاللَّهُ عَلِيمٌ بِالْمُتَّقِينَ﴾
Translation of the meaning
Those who believe in Allāh and the Last Day would not ask permission of you to be excused from striving [i.e., fighting] with their wealth and their lives. And Allāh is Knowing of those who fear Him.
