Abu Sa’id (Al Khudri) reported The Prophet ﷺ was asked “Which believers are most perfect in respect of faith? He replied “A man who strives in the path of Allaah with his life and property and a man who worships Allaah in a mountain valley where he protects the people from his evil.”” (Using translation from Abū Dāʾūd 2485)
عَنِ النَّبِيِّ ﷺ أَنَّهُ سُئِلَ أَيُّ الْمُؤْمِنِينَ أَكْمَلُ إِيمَانًا؟ قَالَ «الَّذِي يُجَاهِدُ فِي سَبِيلِ اللَّهِ بِنَفْسِهِ وَمَالِهِ وَرَجُلٌ يَعْبُدُ اللَّهَ فِي شِعْبٍ مِنَ الشِّعَبِ فَقَدْ كَفَى النَّاسَ شَرَّهُ»
