إِنَّمَا المُؤمِنونَ الَّذينَ آمَنوا بِاللَّهِ وَرَسولِهِ ثُمَّ لَم يَرتابوا وَجاهَدوا بِأَموالِهِم وَأَنفُسِهِم في سَبيلِ اللَّهِ ۚ أُولـٰئِكَ هُمُ الصّادِقونَ

The believers are those who believe in God and His Messenger, who harbor no doubt, and strive with their possessions and their selves in God’s cause. These are the truthful ones.
