At Tawbah, 44 Ayah
9:44
لَا يَسۡتَـٔۡذِنُكَ ٱلَّذِينَ يُؤۡمِنُونَ بِٱللَّهِ وَٱلۡيَوۡمِ ٱلۡأٓخِرِ أَن يُجَٰهِدُواْ بِأَمۡوَٰلِهِمۡ وَأَنفُسِهِمۡۗ وَٱللَّهُ عَلِيمُۢ بِٱلۡمُتَّقِينَ ٤٤
Lā Yasta'dhinuka Al-Ladhīna Yu'uminūna Bil-Lahi Wa Al-Yawmi Al-'Ākhiri 'An Yujāhidū Bi'amwālihim Wa 'Anfusihim Wa ۗ Allāhu `Alīmun Bil-Muttaqīna
Those who believe in Allah and the Last Day would not ask permission of you to be excused from striving with their wealth and their lives. And Allah is Knowing of those who fear Him.
