Surah Al-Hujraatإِنَّمَا ٱلۡمُؤۡمِنُونَ ٱلَّذِينَ ءَامَنُواْ بِٱللَّهِ وَرَسُولِهِۦ ثُمَّ لَمۡ يَرۡتَابُواْ وَجَٰهَدُواْ بِأَمۡوَٰلِهِمۡ وَأَنفُسِهِمۡ فِي سَبِيلِ ٱللَّهِۚ أُوْلَـٰٓئِكَ هُمُ ٱلصَّـٰدِقُونَ
Only they are the believers who believe in Allah and His Messenger, then afterwards they doubt not and struggle hard with their wealth and their lives in the way of Allah; they are the truthful (sincere or righteous) ones
