"I heard the Messenger of Allah ﷺ say: 'The parable of a Mujahid who strives in the cause of Allah - and Allah knows best who in His cause - is that of one who fasts, prays Qiyam, focuses with proper humility, bows and prostrates.'" (Using translation from Nasāʾī 3127)  

سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ «مَثَلُ الْمُجَاهِدِ فِي سَبِيلِ اللهِ وَاللهُ أَعْلَمُ بِمَنْ يُجَاهِدُ فِي سَبِيلِهِ كَمَثَلِ الصَّائِمِ الْقَائِمِ الْخَاشِعِ الرَّاكِعِ السَّاجِدِ»
