(8) باب فَضْلِ مَنْ عَمِلَ فِي سَبِيلِ اللَّهِ عَلَى قَدَمِهِ .
It was narrated from Abu Hurairah that the Prophet (ﷺ) said:
"No man will enter the Fire who weeps for fear of Allah, Most High, 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."
