(18) باب دَرَجَةِ الْمُجَاهِدِ فِي سَبِيلِ اللَّهِ عَزَّ وَجَلَّ .
It was narrated from Abu Sa'eed Al-Khudri that the Messenger of Allah (ﷺ) said:
"O Abu Sa'eed! Whoever is content with Allah as Lord, Islam as his religion and Muhammad as Prophet, then he is guaranteed Paradise." Abu Sa'eed found this amazing and said: "Say it to me again, O Messenger of Allah." So he did that, then the Messenger of Allah (ﷺ) said: "And there is something else by means of which a person may be raised one hundred degrees in Paradise, each of which is like that which is between the Heaven and the Earth." He said: "What is it, O Messenger of Allah?" He said: "Jihad in the cause of Allah, Jihad in the cause of Allah."
