Al Hujurat, 15 Ayah
49:15
إِنَّمَا ٱلۡمُؤۡمِنُونَ ٱلَّذِينَ ءَامَنُواْ بِٱللَّهِ وَرَسُولِهِۦ ثُمَّ لَمۡ يَرۡتَابُواْ وَجَٰهَدُواْ بِأَمۡوَٰلِهِمۡ وَأَنفُسِهِمۡ فِي سَبِيلِ ٱللَّهِۚ أُوْلَٰٓئِكَ هُمُ ٱلصَّٰدِقُونَ ١٥
'Innamā Al-Mu'uminūna Al-Ladhīna 'Āmanū Bil-Lahi Wa Rasūlihi Thumma Lam Yartābū Wa Jāhadū Bi'amwālihim Wa 'Anfusihim Fī Sabīli Al-Lahi ۚ 'Ūlā'ika Humu Aş-Şādiqūna
The believers are only the ones who have believed in Allah and His Messenger and then doubt not but strive with their properties and their lives in the cause of Allah . It is those who are the truthful.
