(8) باب فَضْلِ مَنْ عَمِلَ فِي سَبِيلِ اللَّهِ عَلَى قَدَمِهِ .
It was narrated that Abu Hurairah said:
"No man who weeps for fear of Allah will be touched by the Fire until the milk goes back into the udders. And the dust (of Jihad) in the cause of Allah and the smoke of Hell, will never be combined in the nostrils of a Muslim."
