إِنَّمَا ٱلْمُؤْمِنُونَ ٱلَّذِينَ ءَامَنُوا۟ بِٱللَّهِ وَرَسُولِهِۦ ثُمَّ لَمْ يَرْتَابُوا۟ وَجَـٰهَدُوا۟ بِأَمْوَٰلِهِمْ وَأَنفُسِهِمْ فِى سَبِيلِ ٱللَّهِ ۚ أُو۟لَـٰٓئِكَ هُمُ ٱلصَّـٰدِقُونَ
Innamal muu'minoonal lazeena aamanoo billaahi wa Rasoolihee summa lam yartaaboo wa jaahadoo biamwaalihim wa anfusihim fee sabeelil laah; ulaaaika humus saadiqoon
The true believers are the ones who have faith in God and His Messenger and leave all doubt behind, the ones who have struggled with their possessions and their persons in God’s way: they are the ones who are true.
The true believers are those who believe in God and his Messenger, then never waver, and who strive with their wealth and their lives in the path of God. They are the truthful ones.
