(7) باب فَضْلِ مَنْ يُجَاهِدُ فِي سَبِيلِ اللَّهِ بِنَفْسِهِ وَمَالِهِ .
It was narrated from Abu Sa'eed Al-Khudri that a man came to the Messenger of Allah (ﷺ) and said:
"O Messenger of Allah! Which of the people is best?" He said: "One who strives with himself and his wealth in the cause of Allah." He said: "Then who, O Messenger of Allah?" He said: "Then a believer (isolating himself) in one of the mountain passes, who fears Allah and spares the people his evil."
