لَا يَسۡتَـٔۡذِنُكَ ٱلَّذِينَ يُؤۡمِنُونَ بِٱللَّهِ وَٱلۡيَوۡمِ ٱلۡأٓخِرِ أَن يُجَٰهِدُواْ بِأَمۡوَٰلِهِمۡ وَأَنفُسِهِمۡۗ وَٱللَّهُ عَلِيمُۢ بِٱلۡمُتَّقِينَ ٤٤
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.
Translation: Saheeh International (English)
Each word's meaning and sound
It is not the characteristic of those who truly have faith in Allah and the Day of Judgement to ask the Messenger (peace be upon him)for permission to stay behind from striving for Allah’s sake with their wealth and their selves. Rather, it is their characteristic to rally when they are called to fight, and to strive with their wealth and their persons. Allah knows those among His servants who are Mindful, who do not ask to be excused except for genuine reasons that really prevent them from going with the Messenger.
