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)
"أكملُ المؤمنين إيمانًا رجُلٌ يجاهدُ في سبيلِ الله بنفسِه ومالهِ، ورجُل يعبدُ الله في شِعْبٍ من الشَّعابِ قد كفَى الناسَ شَرَّهُ".
