(17) باب مَا يَعْدِلُ الْجِهَادَ فِي سَبِيلِ اللَّهِ عَزَّ وَجَلَّ .
It was narrated that Abu Hurairah said:
"A man asked the Messenger of Allah (ﷺ) which deed is best. He said: 'Faith in Allah.' He said: 'Then what?' He said: 'Jihad in the cause of Allah.' He said: 'Then what?' He said: 'Hajjun Mabrur.'" [1][1] Hajj, that is accepted, or free of sin.
