(2) باب أَفْضَلُ النَّاسِ مُؤْمِنٌ يُجَاهِدُ بِنَفْسِهِ وَمَالِهِ فِي سَبِيلِ اللَّهِ
Narrated Abu Sa`id Al-Khudri:
Somebody asked, "O Allah's Messenger (ﷺ)! Who is the best among the people?" Allah's Messenger (ﷺ) replied "A believer who strives his utmost in Allah's Cause with his life and property." They asked, "Who is next?" He replied, "A believer who stays in one of the mountain paths worshipping Allah and leaving the people secure from his mischief."
