إِنَّمَا ٱلْمُؤْمِنُونَ ٱلَّذِينَ ءَامَنُوا۟ بِٱللَّهِ وَرَسُولِهِۦ ثُمَّ لَمْ يَرْتَابُوا۟ وَجَـٰهَدُوا۟ بِأَمْوَٰلِهِمْ وَأَنفُسِهِمْ فِى سَبِيلِ ٱللَّهِ ۚ أُو۟لَـٰٓئِكَ هُمُ ٱلصَّـٰدِقُونَ
innamā l-mu'minūna alladhīna āmanū bil-lahi warasūlihi thumma lam yartābū wajāhadū bi-amwālihim wa-anfusihim fī sabīli l-lahi ulāika humu l-ṣādiqūna
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.
Only those are the believers who have believed in Allâh and His Messenger, and afterward doubt not but strive with their wealth and their lives for the Cause of Allâh. Those! They are the truthful.
